Query: Good design, terrible reliability

I ordered one of these from Amazon just over a year ago. Within 2 months, 2 of the LEDs stopped working. They both affected the dim setting, making it too dim to be useful, while the bright setting was still too bright. Since the item was outside of Amazon's exchange timeframe, I went to Kensington and got a replacement. The replacement worked fine for about 6 months, when the first LED went out. A second one went out shortly thereafter. Now last week, another LED malfunction... one of the LEDs has now started flashing, which is very distracting. I expect it to go out completely sooner or later.I've had Kensington products in the past and have been pleased with them. But the FlyLight is too poorly constructed and unreliable to recommend.
