The problem with the solarstorms is that you have ot have a bit of luck whether you get a good one or not.
I’ve opened up 3 of them, all very different inside. I presume because it’s only the casing that is the solarstorm part and they’re getting fitted out inside by different manufacturers with different electronics inside. (Chinese manufacturing innit)
of the 3 the first i had was brilliant, the two i have had since have been terrible.
Worth going for a light from someone who will back up their product. I just bought an mtb light from torchy off ebay and a spare battery.
