Query: Happy with Amazon, not with GE

I purchased these over a year ago; received and initially worked as advertised. Since then one or two have prematurely failed so I called in to GE as they invite you to do for replacements. After waiting on hold for 30 minutes, they were supposed to send a coupon for a new bulb but never did. In general the life on these is better than I have experienced elsewhere but even many of the no name bulbs honor their warranties with better service.
