MAGIC SEAL MS300 Precision Vacuum Sealer Machine, Commercial Double Pump Food Sealer with Built-in Auto Cooling System, Compatible with Mylar, Smooth and Embossed Bags, Extra Wide 8 mm Seal

I have long time experience using nozzle type vacuum sealers. Its the only type I will use. True chamber sealers are too expensive and bulky. Typical counter top sealers require textured bags that get expensive.After many years, my previous nozzle type unit was becoming somewhat inconsistent. I decided time to replace it. So, after considerable research (my wife says I spend too much time researching) I replaced it with this unit. 100% satisfied. Why this unit? First, versatility - it can vacuum seal virtually any type bag - textured, flat chamber, and mylar. Second. it has automatic control and manual control. Third, excellent build quality. Fourth, price was reasonable given it's capabilities.The biggest reason to buy a nozzle vacuum sealer is the ability to utilize flat chamber vacuum bags. When purchased in quantity they can cost a third or more less than the commonly sold textured bags used by most counter top sealers. Having the ability to also use textured bags though makes this model maybe the most versatile sealer you can buy, If I run out of the cheaper flat bags I can go to Target and pick up a small supply of textured bags while I wait for my bulk order of the chamber bags to arrive. Win, win. I like the ability to set both the vacuum time and the seal time. Regarding the seal, the unit has an extra wide sealer element which results in an excellent seal, comparable to that on commercial sealers. No need to do double seals as some units recommend. The unit has a handy built in bag cutter that makes it easy to resize bags without hunting down a pair of scissors. It also has the capability to inflate bags, though I have never used it and am not sure if I will.What could they do to make it better? Two things. First, provide an actual on/off switch. Plugging and unplugging is the only way to power and shut off the unit. Second, a simple cord storage/management solution. The cord needs to be manually looped and tied with a wire tie or something similar for efficient storage. Having a way to wind the cord around a couple of posts on the back would make it a bit less bulky to store on the shelf.All in all 100% two thumbs up.A final thought. The manufacturer refers to using textured bags on this unit as the "chamber mode" to distinguish it from the nozzle mode. This should not be confused with the term "chamber" as applied to true chamber sealers that only use flat, non textured bags. On this unit, it is the nozzle mode that uses the flat chamber bags, same as true chamber vacuum sealers, and the chamber mode uses the textured bags like those used by Food Savers. In any case, this unit can do both modes and they both work really great.

Where do I start? Ok this chamber vacuum checked all the boxes of what I wanted in a vacuum sealer. I chose this one in particular because it seals Mylar bags. There is a larger version of this machine, but for me my bags are not longer than 12 inches. It can also vacuum canning jars, but you have to buy the attachments for large/small mouth jars. It marinated taking the air out of the plastic bag and seals the bag with no mess because it has a suction tube that will catch what comes out. Now, let's talk about sealing Mylar Bags, there is a small plastic piece that comes out to vacuum as much or as little as you like which I use for freeze dried foods that need extra heat for sealing.There are a couple other freeze dryer's that are more expensive and doesn't always fit larger bags for large roasts or foods like that and you might have a mess after it's done vacuuming and sealing. It's a very good machine.

Vacuum sealer seals Mylar bags excellent. It has different settings for sealing mylar bags which is good as to see what settings are ok for the thickness of the bags your using.

We've been putting the MS300 through it's paces and have so far been really impressed. We have a Harvest Right home freeze drying machine and use this vacuum sealer to pack our freeze dried food into smooth mylar bags for long term storage. The chamber style vac machines are much larger and more expensive - I'm for sure sold on this style of vacuum machine being a better overall solution. Note that there is one very important detail mentioned in the owners manual that makes all the difference - and that is that once the food is in the bag and had been clamped down - you need to manipulate the bag contents and push it forward towards the vac nozzle. When we do this we get great sealing results. This model also has a fan that blows and cools down the heat seal strip so that you can use it continuously without damaging the machine. This new feature works great and in my opinion makes this the best model in Magic Seal's lineup. Oh - and the customer support is great as well. All in all I would not hesitate to purchase this machine again.

The only two flaws are:1. You really have to treat it like a MAN. LOL2. The lack of an on off switch. Not a biggie you can buy one.EXCELLENT sealer. Zip lock? Set it to 3 0r 4Mylar bags? Set it to max. Seals it all and the seal is over twice as thick at 8mm. Very good device!

I bought my Magic Seal in April, and have been very happy with it. Recently though, the vacuum chamber feature stopped working. The pump would run, but it stopped drawing sufficient vacuum to seal the attached canister. I looked inside the Magic Seal unit and noticed a small crack in the plastic where the vacuum hose attaches. I called customer support to see what my options were. Within 30 minutes, they had boxed up and shipped a new replacement unit. These folks have exceeded my five-star rating with their customer support. I'm impressed!

I am beyond thrilled with my Magicseal unit! I love the fact that I can vacuum both mylar and textured bags. Best of all they sent me FREE OF CHARGE an accessory to seal my mason jars! It works like a charm! I bought a battery operated jar seal that didn't even work and had to return! Please add an on off switch or even one to the cord.
