This was my first ever vacuum sealer machine. It was a impulse buy because I wasn’t sure if I’d use it or not tbh so I got something in my budget that would break the bank but also would be a great intro to vacuum sealing. First, I’d like to say I like the size of it. Very convenient to stash away when not using if you don’t have much counter space. The YouTube videos on how to use it is nice, easy to understand, and explains well. Second, it is a trial and error type of machine. You have to follow directions and do everything correctly to vacuum seal things properly, so it does take some practicing (don’t get frustrated on the first try! Like me!) It definitely took me more than one try to get it down. I like that it doesn’t seal the bag until it is correctly in the machine so even if you mess up, you won’t waste the plastic bags because it won’t seal. This allows you to readjust and try again. I’ve only used it to seal the plastic bags. I don’t have containers that allow a vacuum seal hookup but that extra accessory is nice to have if I ever do buy some. Lastly, It’s not a big machine and the bags don’t hold a lot because you have to leave room to seal them, but I am a house hold of 2 and it’s perfect portion sizes so far. I will definitely be buying more bags. The machine has already paid for itself with me being able to vacuum seal a bunch of different meals I made a lot of to save for later.I've had this machine for a few days and I'm impressed. It has good suction for a inexpensive machine. It's light weight and it doesn't take up alot of counter space.It does its job and it does it pretty well. My only real complaint is that you have to leave 2-3" of plastic at the end or else it won't suction or seal correctly. Seems really wasteful. Sometimes it feels like it should be suctioning more air out of "moist" foods (e.g., chicken breasts). Otherwise, it does its job. Vacuum sealing is weirdly fun and satisfying. For the price, it's awesome.I was disappointed that there are no jar tops to hook the vacuum tube to. I ordered a set but the tube connectors did not fit.I love it, saves my leftovers and all my green leaf vegetables and all veggies.Seals great , as long as you preheat it first!I learned that after a couple of times using itMy previous, super expensive sealer but the dust after 3 yrs, so I got this one. At time it seems to lack suction and I have to reposition the bag, but all in all worth the price.Bonus points: it comes apart to actually be able to clean the bottom tray of any juices sucked out during sealing!Instructions not very good. Works well after I figured it out. Definitely a 4 for the price. Sorry for the confusion.
