It worked only for 10 minutes.
It is made of soft plastic that bends and does not allow the gap to be created.

In relation to its price, I would say it is satisfactory. I have only used it for meat, but it needs attention to ensure that it does not contain any liquids during the vacuuming process (e.g. from marinating).

I bought it,,,everything was fine at first...but after five uses, it stopped pulling air from the packaging,,it only stuck together,,not satisfied at all,,

Very good for its price (VFM). It seals hard foods perfectly (cheeses, nuts, etc.) as well as softer ones like meat, fish, etc. for refrigeration/freezing or sous vide.
It has two functions, the simple sealing and the vacuum that first sucks all the air and then seals it. From my experience, it works better with textured bags (it stretches better as the bag embraces the food better when all the air is removed) although I have also used smooth ones and they still did the job.
It also has a special tube that you attach and it sucks the air from containers that have a valve on top.
Of course, I have to point out that it is NOT INTENDED FOR PACKAGING LIQUIDS as one of the other reviews mistakenly did and it ruined it because it is an air suction device, so inevitably, in order for the bag to "stretch," it will start sucking the contents... If you have something that is liquid or contains a lot of liquids, then you can simply seal it without sucking the air from inside.
In conclusion, if you need a vacuum sealer for household use (because after each sealing you have to wait ~40 seconds), I highly recommend it.

UPDATE 23/4/2023

After a few seals since I got it, I noticed that it no longer seals tightly on its own but needs pressure from above with your hands while it's working (like you do on a toaster) to close completely, so it continues to work just as well as the first day. Apart from this issue, it does an excellent job for its price.

I bought it relatively recently. The impressions so far are very good. It completely removes the air and sticks very well. I think it's the best in terms of value for money. I will come back in time regarding its durability! P.S. Its only drawback is that you have to use its own bags. 27.06.2023 One and a half years after the purchase, the machine works equally well!

I give 1 star because it doesn't have an option for anything. In the first use of the vacuum, instead of sealing the bag with the kombucha, it sucked up the liquid and of course short-circuited. The instructions don't mention anything about not trying to seal a bag with liquid. Unacceptable, all of them in everything.

Very good and economical. It sucks all the air through the bag and you can stop it if you want to have a little air inside. I also bought reusable bags RCO9003022, which you cut from the packaging to the size you want, seal them on one side with the device, then fill them and it sucks all the air. I didn't expect the machine to be so good, I am very excited and I have been using it many times in the last month. It didn't show any issues at all. Very reliable brand in general, I recommend it to those who want a quality sealing device with low cost!
