A few days of use, and I'm pretty happy but no more. The power is not too small, but enough anyway. To empty the bag recovery sanding residue, better undo all rather than using the zipper is hard and stuck easily. The machine "eats" a little tape on the left side, but it could be worse. The button for continuous operation maintenance is average. Otherwise you can use it several hours later without any problem what is good, it heats a little but this is normal and there is worse.
