Question: Any problems with overheating?  How many bags can you seal at one time before it overheats?
Document: I tried putting a paper towel over the snorkel to keep it from going in and that did help, but I didn't get a good seal on one of my bags because flour got around the top of the bag. Next time I will try to put my dry ingredients into a zipper type bag first leaving the top open some, then put that bag into my vacuum bag just to see if I can get it to seal properly.
The Sinbo was what I was looking for in a vacuum sealer machine, because the food saver machines will not vacuum seal mylar bags unless you finagle them to do so. The sinbo does the mylar bags well and also less expensive vacuum bags, so it saves money. I had been looking for a sealer that does mylar bags and this one does. It takes getting used to.
I have been very happy with this item! I bought it to seal mylar bags and have gone though at least a 100 bags so far with NO problems. If your looking for a sealer to seal 4 mil mylar bags look no further.
I wasn't expecting too much, and that's what I got. The machine seems to seal OK, and that's what matters. I sealed a few test bags of almonds, and will wait a month or so and see if the contents stay fresh. Two minor issues; the Power button doesn't light up on this one (maybe yours will) and the vacuum pump doesn't shut off automatically as it says it will in the instructions.
Would not seal! The vacuum worked, but it did not seal. I returned it and hopefully have better luck next time.
I love this product. We use it all the time as I buy meat in bulk quantities and then vacuum/seal and freeze. We also butcher our own wild game and use it for this purpose.The sealing does take some practice. I noted that another user commented on this in their review.
Good Concept, BUT SERIOUS ISSUES - So, I'm Building My Own Sealing ApparatusGiving this a 3 star for the ability to SLOWLY seal ANY bag. Otherwise would get a 1 star.Without exaggeration, one can draw out air faster with a straw and draw out MORE air than this machine, and then depress a bag sealer across the bag and do a better job! I tried it and did it.Most evident flaws is that the seal switch is intermittent due to a design flaw.
?The drybag type of bag will allow moisture to escape (after vacumning and sealing) but will not allow oxygento enter. This is necessary in order to properly dry age beef using a vacumn/sealer device.Also I might add that adjusting the 'time limit' value seems to be rather arbitrary. Yet very important to set correctly in order to obtain a accepatable seal. Otherwise you are just wasting time and money as wellas that expensive steak.Come on Amazon..you can do better than this.
Item was shipped in record time!!! Had to contact customer service....immediate response.....new sealer was sent....immediately. Love my sealer....seals Mylar bags which my food saver does not do. Very pleased with my purchase!!! !
Make sure you get good quality bags. It works better with thicker bags. In 10 years, we have done over 2000 vacuum seals with it and the vacuum holds for years. We have replaced the tape covering the heating filament and the tubing inside. There are also some plastic pieces fell off. Other than that, it is still working well after 10 years. We are going to buy another one soon just in case the old one die eventually.
Answer: About 15 or 20 of the 1 gallon bags... im not sure if the machine itself overheated or if it was the sealing strip.so I gave it a break for a few minutes and went back to it again. I am very happy with the machine. There is a learning curve but once you are used to it, its a breeze.  Happy prepping!
