The one I had before was difficult to adjust the speed, so it was easy to make holes, but this one allows you to press about 8-10 cm at a time, which is very convenient. Also, you can adjust the time, which is nice. I tried using an envelope I had at home and it worked very well.
Most of the sealing machines similar to staplers either don't work properly or cut the plastic while sealing, but this one definitely works well. The sealing part is not just a thin wire but quite thick, making it a different level from portable ones. Although the manual is translated, it's in several languages and even includes Korean, which was surprising. It operates intuitively and cleanly, and if I had to find a shortcoming, it's that it's mini so the sealing length is a bit short... It can only seal about 1cm shorter than the body length on each side. But after using it for a while, I got the knack of it, so it's not that inconvenient, and I'm very satisfied that it seals properly.
Wow, an incredible machine for sealing bags!! I didn't have much confidence, but when I opened it, apart from the fact that it comes 100% charged (and includes its Type-C cable for charging), it works perfectly. In addition, it comes with an instruction manual in all languages (which is always appreciated), it's very easy to use. I recommend it 1000x1000!
I bought it to try without much expectation. But it surprised me quite a bit. It definitely delivers what it promises. It has 6 time levels for sealing. It surprised me. Those who are in doubt can buy it without hesitation! 5*
