VOLTRX Electric Shaker Bottle - VortexBoost Portable USB C Rechargeable Protein Shake Mixer, Shaker Cups for Protein Shakes, BPA Free, Waterproof, Colored Light Base, 24 oz (Aurora Green)

Very useful, high quality bottle with strong blender that doesn't leak.Pros-Strong blending mechanism-Does not leak, has a sealed cap-Plastic handle on top makes it easy to carry around-Machine washable-Reasonable price, would buy again-Not slippery, the plastic gives a good grip when holding the bottle-rechargeable bottomCons-Sometimes hard to open, makes a mess if you try to open itOverall, good product, would buy again but would be great if there was an easier way of opening.

Update: Customer service responded to my inquiry within minutes and is sending a replacement. We haven’t received it yet but 5 stars for the response time and attentiveness to our broken blender.Great product until it stopped working. Had it for 3 months before it gave out.

Great item, I like that you can remove the base to protect it from water while washing. Easy USB-C charging port, no leaks and no issues with it so far.I mix my protein powder in it with some water and usually about two cycles will make the liquid smooth. If you double tap the power button I notice that it'll make the unit run longer. Either way, it's much easier to blend than shaking alone.

UPDATE:OK, so the company reached out to me and reported that their response to me was delayed due to a fault in their system on their end. The person I worked with was more than fair in their solution, and ultimately replaced the original cup I had which was leaking. So I have raised the review from 3 stars to 5 because of the following-Once the company reached out, their customer service was excellent and they got a replacement product out QUICK.-The replacement product worked as expected (ie, doesn't leak.)-The mixing really does work super well WHEN MIXING PER THEIR INSTRUCTIONS. I'll point out that the difference between "mason jar" quality mixing and "it really doesn't need a mixing ball because there's no clumps left" is whether you are adding water and then protein powder (which I was already doing), and holding the cup vertically when mixing (which I was not previously doing).-All of the positive things from the review below remain, including being super easy to clean, nice wide mouth to pour powder in, feels well made, etc etc etc.All in all, this is my first mixer cup (so you can take that into context as well), but I am glad that I purchased this as it totally satisfied my desire to have something simple/easy to clean, quiet, and effective for mixing protein powder.Original review below with updated edits in brackets:As a bit of context for this review, this is my first shaker bottle. I exercise from home, so I don't need to travel with it, and I also exercise before anybody else is awake in the house, and didn't want something noisy. Previously, I was using a mason jar w/o a mixer to mix a whey blend protein powder. I don't have a ton of experience with protein powders at this point, but do know that this tends to clump more than some others I've tried. I wanted to try a mixer bottle that had a wider mouth, but didn't want to mess with a widget inside that needed to be cleaned. I'm lazy like that. So as I provide a narrative summary for this review I will be outlining my thoughts on the "about this item" bullet points for this item, and I am generally going to be comparing this to a standard, run of the mill mason jar.In reverse order:Leak proof guarantee. [the company eventually reached out and send a proper product that doesn't leak, so the remainder of this becomes for history only] This seems to be faulty on two notes. First, yes, it does leak (or at least mine does). That's the first thing I noticed about this product, and I initially thought I was missing a gasket, but I see now that Helimix claims that a gasket is not needed. Well, I can't say that to be true based on the product I was sent. I did reach out to the company via the channels suggested, and haven't heard back (it's been almost a week) [it ultimately took 8 days for them to reach out to me, but they stated they didn't get the original message]. I realize this can take time, but Amazon has already sent a followup email asking whether my problem has been resolved, and as I haven't heard from Helimix, it hasn't. So I wouldn't say it's leak free, and I wouldn't say that they are making sure that they are resolving issues (or at least if they will, they haven't yet). At this point I'm just trying to tighten it as much as I can (much more than I would expect that I'd need to) and sort of hoping for the best. This does help, though it makes me wonder whether there will be longevity of the lid. I will say that the amount of tightening necessary to reduce leaking makes it hard to unscrew, as the cap doesn't have any traction on the outside for grip. In fairness, after about a month of frequent use, the mason jar might have leaked twice. But so far, it seems that the mason jar edges out the helimix for this.Durable and easy to clean. I would say this is true. The product seems sturdy throughout, and while I haven't stress tested it in any meaningful way (aside from VERY firm tightening/untightening), it seems like it won't be falling apart any time soon. It does seem easy to clean as well. I don't travel with this cup, so I tend to rinse it right away and I haven't noticed any areas where powder tends to clump that I can't get to when it comes to cleaning (more to come on that). Before ordering I had some concerns that the powder would get caught in the lid, however the inside of the lid is domed and there's nowhere for the powder to get caught there, and the mouthpiece is large enough to clean inside so there's no issues there. I like the very wide mouth, as I can fit my hand to the bottom with a washcloth. If the mason jar I have were wide mouthed, I think it would potentially be a draw for various reasons, but I like how the helimix is big where it needs to be to make cleaning easy vs the "standard mouth" mason that I can't fit my hand into.Odor Resistant. I can't speak to this. As stated, I wash (or at least rinse) this immediately after use, so I don't really give it a chance to sit and absorb. It doesn't smell yet, but it's only been about a week. The mason jar didn't smell either. So a tie I guess.Superior Supplement Mixing. [having a product that seals correctly AND me mixing correctly, ie vertically, made all the difference... and yes, it mixes beautifully! The design of this cup really is clever and effective!] OK, this is a tricky area to speak on. In the packaging itself there aren't any instructions for use, though one wouldn't expect it needs to be any more complicated than "throw in the stuff, close and shake." I do know from limited experience that it's best to add the water THEN the powder, so I've been doing that. Now somewhere online it also suggests to shake the cup VERTICALLY, as this allows the shape of the cup do whatever the shape of the cup is supposed to do. Unfortunately, I haven't yet tested it in that way, as I have some real concerns about where the contents of the cup will end up if I do that. Instead, I've been shaking it downward into the sink, so at least I'm controlling where leaks go. So if I'm not taking advantage of the "technology" of the cup by shaking it correctly, it's a bit hard to tell whether I can fairly assess it's ability to mix. If shaking it vertically was also super important, I kind of wish that bit of information was clearly communicated inside or on the packaging rather than only somewhere online. That said, my inclination is to say that it "probably" does a better job than the mason jar... maybe? In both cases, it involves some shaking, some looking into the cup/jar to see whether I can see chunks, some more shaking, and so forth. In the end, some days there's a chunk left over, and some days there aren't. Sometimes there's a little unmixed powder hiding in the mouthpiece, and sometimes it comes out totally clean. I haven't really figured out the magic of consistent and completely blended results yet. I feel like it maybe takes less shakes with the Helimix, but I have to say that my experience of shaking them are different as I sort of walk around and shake the mason jar absentmindedly, and I shake the helimix rather purposefully into the sink as I watch for leaking. Maybe a slight edge to the helimix, but if I'm shaking it "wrong" due to shaking it upside down into the sink, then maybe it's not a fair comparison.No shaking accessories needed. [True! When tested with a whey protein isolate, as well as a whey protein isolate blend, no blender ball or "excessive shaking" is required to get a completely mixed shake.] As a stickler for the word "need," I'd argue this is true. It isn't NECESSARY, and wasn't in the mason jar either. They both mix the contents without a widget. If it's not mixed, just keep shaking. Not much to say here, as neither thing needs one, or at least they both function about the same without one.So pros and cons... [With a proper/non-leaking cup, I have to say that for me it's all pros! Absolutely an upgrade from a mason jar. So if it leaks, contact the company, and when you shake it, make sure it's vertically as this totally matters!] The Helimix seems well made, mixes well enough I guess (though my ability to use the product as they recommend it is hindered by the leaking), I love the wide mouth both for pouring mix in and access for cleaning, and it IS easy to clean (which was one of my main concerns before purchase). That said, the fact that it leaks is disappointing, especially since it's guaranteed not to, and more so when coupled with lack of outreach from the company to address my concerns after I've inquired for help with this issue. I'm hopeful that the company will reach out at some point and either tell me what I'm doing wrong (do there need to be tips/tricks for screwing a cap on?), or that I have a faulty product. If nobody outreaches however, I may end up trying to return/refund this and just buy a wide mouth mason jar.

The media could not be loaded. This cup with a built-in mixer is incredible! It makes blending protein shakes, pre-workout, or any kind of powder mix effortless — no clumps, no mess, just a perfectly smooth drink every time. The motor is surprisingly powerful, and you get multiple uses out of a single charge, which is super convenient. It’s lightweight, easy to clean, and honestly just makes life easier if you mix drinks regularly. I wish I had bought one sooner — absolutely worth every penny!

This blender works really well for mixing up protein and creatine powder! It has a solid design and great battery life and not too loud. Their customer service (Judith) is also fantastic and they replaced my blender after I dropped it off a counter and broke the locking mechanism for the motor. I have recommended this to several friends.

Blender seems to do well if it has a full charge. Afterwards it seems like it spins, but can't actually stir the fluids. I only used a 12 ounce shake mix in it. Nothing extra nor added to it. I'm trying it again to see if it remains a problem.

The cup looked and worked well at first. I initially only used it a few times a week for mixing protein powder. After the first month I began to use it more often always hand washing and was careful never to drop it. Shortly after steady use one of the plastic locking ears literally disintegrated causing the power base not to work without falling off. The company did reach out to me and offered a replacement of my choosing and was immediately shipped. On the amozon listing it states there is only a 30 day warranty but the company will stand by their product for a year.
