Not hatin, or flamin'. I can only speak from personal experience, but I'm on my second front frog light that won't turn off. You click through the cycle, but it never shuts off. It'll shut off for 5-6 seconds, then kick on the cycle all over again. The LBS replaced the first one, but now after 2 months the replacement is doing it.
I cycle through a relatively lit area at night, and the frog was an awesome addition to the wal-mart bell lighting kit I have (never failed me, but the lumens the frog has was far far superior).
Is there anything relatively close? Perhaps another brand biting off the frog style? Some googlefu has revealed that I'm not the only one with the trollface.jpg, frog not wanting to turn off hootananny.
