Fantastic price, great design and features and appears to be good materials and build quality - Variable speed increases torque as load is applied, reversing switch has a nice time delay, very little runout and good fit/finish. I was very impressed with the value... until I tried drilling the first hole. As soon as there was a load on the motor I got an electrical arc between the cutter and the steel plate I was drilling and sparks out of the motor brush housing. There is apparently an internal electrical fault that became apparently only under load, so understandable it made it through final QC testing. I'm hoping it was a one-in-a-million anomaly and have ordered another one to replace it while applying for a refund for the faulty one. I'll update my review when I get the replacement. I really WANT to love this tool!
