Query: Get me once, shame on you. Get me twice, shame on me.

Unfortunately,I bit on this twice. Bought one in 2009 and it lasted 16 months. 4 months out of warranty. Bought another one in April of 2011 and it lasted until June 26th 2012; two months out of warranty. Same issue, brush drive shot. I will not try for third time's the charm. I would stay away from this unit.
