I like it. The one thing it seems to be missing is MIPS.
Can you confirm what kind of battery it takes.
CR2032 button batteries are more or less compatible with LIR2032 rechargeable batteries. A bit of a pain to charge, but certainly possible to do.
I like my Bell Surge TF19X
It uses really tiny little button batteries, CR1616. I don't run them all the time, but they'll last for a while. And spare batteries are dirt cheap if one buys in bulk on the internet. One nice thing about the Bell is the right and left lights are independent. I usually only run one side at a time, so I have the other side ready to go.
