PolyScience 150 Series Vacuum Sealing System, 120V

Don't worry about the negative reviews here, they have failed to read the manual. You need to firmly press down the sides of the cover and let them hook in with a click. After that just push the buttons and it takes care of the rest! I have used it with my Avano Precision Cooker sous vide for about two months ~15-20 bags with a maximum length of 20h cooking. No issues at all.

works great. it was a gift, and tried it out--love it. it's nicer than the one i have (the larger polyscience vacuum sealer).

Stay away form this vacuum sealer. Had it for only a week and it failed to completely seal my items 3 times. Failing to seal completely would not have been that bad had I not been using it for Sous Vide where you vacuum seal your food and cook it in a water bath. So when the seal failed the leaky seal filled the food bag with water ruining the food. Also I had to forcibly push down the lid to get it to seal at all, something I only had to do with my old vacuum sealer after many years of use. Due to it not sealing completely I returned this after only 8 days of use. Will stick with Food Saver brand from now on.

Great seal

This is not a quality product. It's honestly surprising, and kind of a bummer, that a company as quality as PolyScience would put their name on it. The one time I tried to use this i could not get the locking mechanisms to catch securely and therefore could not get a proper seal. One side would catch and then I would have to manually pop the other mechanism out to try to get that to catch at the same time. Never really worked. Wasted a bunch of bags trying to get it to do so. Will avoid using again at all costs. If anyone has any suggestions on anything better in a similar price range, or a bit higher, please let me know! Thanks.
