alright i just bought a dremel 400 xpr or wahtever,... anyway thing works fine but i just took it out of the box and the dust cover or wahtever ontop.. doesnt close all the way.. it stays in place but its not sealed as well as it should be imo.. it doesnt affect the operation at all and a piece of tape would fix it but i just did spend like $80 so i was just curious if this is a common problem? and i know this might not the right forum but i know alot of ppl on here use them
