Missing parts, poorly formed plastic, poorly placed dust holes make this a bad buy. this is sand That's why I bought it. I need to buy the missing part and can't use the extra dust bag for the 5 inch wheel. The plastic hasn't been molded properly so it doesn't line up with the screw holes, it's missing the 5/8" mark. Huge mistake. However everything works because if I could attach this dust port it would interfere with the right table adjustment knob. So instead I settle for knees covered in dust. Thank you Powertek. This guarantees that this will be the first and last product I will ever buy from you.
