WASTED MONEY
Upon receiving it, I tried it and it only worked at full speed. It did not work at all in the speed adjustment positions. I returned it and they gave me another one. The second one worked fine, but on the fourth use, it stopped working. From the day I bought it until it broke, the total usage time was 15-20 minutes.

I have had it for over 1 and a half years and with relatively frequent use, I have cut some plastic, a little bit of iron from a PC case, etc. For the very simple tasks that I bought it for, it does its job well. Of course, it will struggle if you try to cut concrete bars, fences, pallets...

Useless even for the amateur use that I give it. The gears fall off with the slightest force, until the axis stops rotating! Don't buy it, you will cry for your money!
