Sealing bags is a piece of cake.
The Ruruii brand manual impulse bag sealer was precisely what I needed. I had previously sealed packages only with a hot air gun, but the results were poor. Many bags had plastic overhanging, and I had to cut off any excess with scissors. This is more work. The result is that the packages were poorly packaged. The Ruruii bag sealer, however, has proven to be highly effective, ensuring a perfect seal every time and boosting my confidence in the quality of my packaging. This machine, the Ruruii brand manual impulse bag sealer, is the ultimate solution to all of the above. It boasts unique features that set it apart from other sealers. Let's delve into some of these features: • I like the blue color of the machine. • Its dimensions are: 15.7" (length) x 3" (width) x 6.93" (height). • It weighs 3.5 lb and is lightweight. • It doesn't require a warm-up time. Before connecting it to the power supply, set the temperature as indicated in the instructions. I used it on mode three, and the job was perfect. • It's incredibly user-friendly. Place the bag over the original seal and hold the handle for 2-3.5 seconds for an optimal seal. I discovered that I can easily tear away the excess plastic, leaving a perfect seal. In conclusion, the 12-inch impulse sealing machine for plastic bags has exceeded all my expectations. It has not only solved all my previous delays and inconveniences but also saved me a significant amount of time. Sealing plastic bags is now a quick and efficient task, allowing me to be more productive. I no longer waste bags on poorly sealed ones, making it a cost-effective solution. Based on my pleasant experience, I recommend this fantastic sealing machine from Runruii and rate this review 5/5.

Works great for diving up vacuum-sealed bags of food for freezer
I store a lot of food in my freezer, whether meats I've sous-vided, veggies I've frozen, or even things like croissants and such. I vaccum-seal them all in standard sous vide bags, so that I don't ever have to worry about freezer burn -- it doesn't matter whether I reheat that croissant in the toaster oven 5 days later or 10 months later. But I generally want to reheat just a single portion -- a single steak, a pair of chicken thighs, a single croissant. But using my vacuum sealer to vacuum and seal both sides of each individual steak, each individual croissant, takes forever. So I do them in a long row -- a single long bag with 5 steaks spaced out, or 8 croissants spaced out. I seal them at once, then I use this to create seals *in the middle* of the bag, in between each individual item. This way I can cut open the end or cut off a single pouch and reheat a single portion without breaking the seal on all of them, and I don't have to use my vacuum sealer again to re-seal the rest. This works great for that. It does exactly what I want. I was worried because I saw a lot of negative reviews about it not making a good seal, not making a consistent seal (better towards the hinge), or the bottom of the unit melting or something. In terms of making a good seal: you have to figure out the right number to use and hold it down long enough. E.g. my sous vide bags don't get a consistent seal on #2, but on #4 it's perfect. The light stays on for only about a second and that doesn't produce a good seal, but holding it down for 6 seconds produces a perfect seal. If you're not getting a good seal, increase the number and/or hold it down longer. In terms of consistency: there is no difference in the seal closer to the hinge or further away. But it does make contact close to the hinge first, so I have to guess this is people closing it and opening it slowly, and not holding it down for long enough in between. In terms of melting: I'm only use this to make 15 or 20 seals at a time. Nothing is getting hot or melting on the bottom, it's fine. I can't speak to whether you could use this to seal 1,000 packages in a row over the course of an hour though. Obviously at some point it might overheat, and I don't see any indication of a safety mechanism to automatically shut off once it gets above a certain temperature. So it works perfectly for me. My two main complaints are: 1) The packaging is impossible to open, because they glue-gun the cardboard box shut, and the cardboard is extremely thick and heavy-duty. You basically have to destroy the box to open it which means a return would be an ugly thing. 2) This thing is super ugly. It definitely looks like it belongs in a factory, and not an office or kitchen. I don't know why nobody manufactures an attractive version of this? DOTPRO sells an 8 inch one that's vastly more attractive, but sadly not a 12 inch one like this. But this does the job and it's inexpensive, so it works. Even though it's ugly, I'll still give it 5 stars since it's obvious from the photos that it's ugly. I knew what I was getting.

Great item
This is the most awesome thing ever!! I absolutely love sealing and shrinking and making things look more professional for my eBay business. Best purchase for sure. Great price, works good, and they give you an extra strip.

It works.
Works well. However... Poorly translated documentation. Several warnings about running this unit on it's higher settings for any length of time. Perhaps a desperate attempt to make this unit more flexible at the expense of product longevity. Just design the unit with lower limits and you have a better product. These days it's more important to make a price point. It does come with 1 extra set of heater consumables. It does work fine for me on lower settings, so I hope to get some life out of it before I have to start spending money on it. I was looking for a slightly more expensive unit that was of higher quality, but could not find one. Even though there is about a 50% difference in price between them, all these products look like they come from the same assembly line - just stamped with different goofy brand names. The more expensive clones appear to be bait for a person like me, if I was a little more gullible.

Great hand bag sealer
Bought this as a backup to my broken conveyor sealer and I now use this more often. Works great, seals quickly and operates as advertised.

Perfect
I’m really happy with this impulse heat sealer! The 12-inch size is perfect and seals bags quickly and tightly. I’ve used it on different plastic bags (PE and PP) and every seal comes out strong with no leaks. It’s very easy to operate—just plug in, set the seal time, press down, and it’s done in seconds. I like that it comes with extra replacement elements, which makes it a great value. The build feels sturdy and durable, and it works exactly as described. Perfect for packaging, food storage, or organizing items. Highly recommend thanks
