Query: What Happened?

My company has one that I use at work. The thing is great! The motor is strong and the blades sharpen well. The one I purchased online does not sharpen well and the motor has frozen. I have to unplug the damn thing to stop it and plug it back up to start it! Sometimes it just stops and I have to wait 10-15 minutes until it decides to start again! I know it is the same model number as the one at work because I wrote it down to order one for my home! Bostitch had an excellent reputation. What happened with the sharpener that you sent to me??????
