Send it back for replacement.It should have a warranty for at least 6 months.I'm not sure if any of you have heard of Kenco Beauty Supplies, but they sell a micromoter drill, and my hand piece started making a high pitch squeal and I have no idea why. I've only taken the best care of it, never dropped it and I've only had it for 2 weeks. I don't really know what to do. I dont know if they'll replace it, but I think I want to go with a smaller drill, but I still want the torque/power and quality.
Any suggestions of what I should do?
