At first I was apprehensive about this tool but upon receipt I was pleasantly surprised by its good grip and speed setting, even if it is surprising at first, because it's still strong. I gained a lot of time in the sanding my staircase, my only regret would be the limit of 4 accessories in the cabinet, but I bought additional accessories. The user manual does not present all the accessories which I have not tried much but you can easily find information on the Internet. Effective and above all useful for different works, I recommend this tool for those who want to save money and not to multiply Sanders purchases.
