I bought this because of good reviews and watched the videos online. Very simple to set up and use. But there are few flaws that made me think twice. This is a very dangerous machine so nothing should be left to chance. 1. The manual was absolutely useless. All the diagrams were in a separate page and the instructions were unclear. 2. The installation of the blade was not obvious, as I needed to insert it in a tight gap while holding a sharp blade. The instruction did not mention anything about that so after many attempts I resorted to watching a video, which I luckily found. 3. There is a video scan on the manual to go to the video. It required installing an app which I deleted immediately as it was full of virus. 4. There is no power switch. There is one that has a on/off icon right on top but that is for the laser so I assumed it was for the power and did not realise I could have accidentally turn it on again. Very dangerous. 5. The feature that made me to give 1 star is the slider bar next to the cutting slit. It was set to the right by DEFAULT which meant, if I had not read the useless manual to the end I would have not know about its function. My very first cut was 45 degree, so when I did the cut I realised I cut through the slider. And when I looked closely there is a warning sign on it. That is totally unacceptable. The slider should never go under the saw in the first place, at least it should have been put to the left with and tapped the warning on it so I can see the warning before removing the tape.
