Brilliant for the money,
Verified Purchase(What is this?)
This review is from: Prowell Sharkfin LED Helmet Light (Misc.)
I've had the Topeak helmet light for a year, but it's such a nuisance to attatch to detach that I stopped using it
This is much simpler to take on and off. It's not my main rear light, obviously, but for a fiver I think it just gives you that extra visibility to drivers.
