After unpacking this discsander I was disappointed with the sub standard finish of the castings particularly around the housing of the disc. It seems they don039t have much of a quality control system in place at even a basic level. I almost packed it up and was going to send it back but I decided to try it out and shape some wood I had lying around and I must admit surprised. The motor is quite powerful at 500 watts and it easily sanded the wood I presented to it a various pressure levels. It did not stall at all. It also is not that noisy. The tolerances on the slider bar leave a lot to be desired but quite usable and overall not too bad. It is a shame that they could not get the castings right or at least reject the ones that donrsquot come out of the mold square and proper. I may be a bit picky but 90 degree angles on the base corners should be 90 degrees not 80 degrees etc. Overall I guess at the price I paid compared to the competition it has a more powerful motor and does the job easily and was significantly cheaper. I just throw a rag over it in my workshop so I donrsquot have to look at it when I am not using it..
