I went though a lot of these vacuum sealers after my entry level machine broke. I forgot the name but you know the ones you can buy at any target, Walmart. The broken one was good and lasted but I wanted to upgrade to something more powerful. The problem I was having was the strongest motor vacuum sealers i tried were loud. This is a serious vacuum sealers and apart from a few slight things that I wish this had it was by far the best one I tried.The downside aspects for me first. The biggest thing is the way it is setup you can't seal without first running a short vacuum pressure when you want to seal a bag. You have to push vacuum and then seal. It makes sense because of the way its set up. When you press seal the chamber closes forcing a tight grip on the bag in order to seal it and the seals are strong because of this. This is not a big deal at all you get used to it in no time but it was something that i wasnt used to at first. No big deal.The second thing that I was used to was having a bag cutter on the machine. The machine doesnt hold a roll of bags. To me this was perfecrly fine and a waste of space. I buy those bags in a big container and rather them use the space for a roll holder use if for the motor and sealer. Again this was no big deal for me as far as not having a bag cutter I just pull out scissors from the draw and cut my bag.Something I wish it had was a dual seal. Instead of one seal two separate seals that make it extra srtong.Those are the only down side to this and other than that this thing is great, powerful and the seals are strong. It is fan cooled and quite. Much more powerful than my old machine with possibly even less noise. How well this is built and how strong the vacuum is far out weights the few things i would have wanted on it.After i got this sealer I stopped looking because it had the two biggest things for me to find. A powerful sealer that isnt loud. If they included these things into this machine it would be ideal.The construction, motor and how quite this machine is top notch and it took a bunch of time researching and ordering others to realize this was by far the best machine I was likely to get for home use.( the brown box to the right of the sealer is bags I bought from Amazon. Also a good buy. It has a cutter on it and makes it easy to get the right bag lendth)
