I have both convoy and jaxman.
I choiced jaxman as they sell nichia version. nichia really help my job and eyes.
I use lights every day as an aviation mechanic.
I often drop the JAXMAN light and use it roughly, but it hasn’t broken down for three years.
On the other hand, my colleagues’ typical China lights often broke down.( In fact, famous brand lights are also not durable… nitecore,armytec,zebra lights,skilhunt were not durable to me…)
For the price I agree that convoy is the best
My next light will be jaxman 21700 M3 nichia version. (with forward swith)
