Query: Electronics failed after very little use

Received this blender as a wedding present and used it a handful of times before the control buttons began to exhibit flaky behavior and it wasn't long after that when the unit would not reliably turn on at all. Thumping it with one of the buttons would get it moving, but it would not stay running. Having experience with a couple other models, I would recommend either a $25 Oster for basic needs or go for a $400 Vitamix with the brute strength to do anything and do it for years. A mid-level model with these types of issues are a ripoff.
