Sounds like the cygolite rear is a good light but anyone considering it should know that it is not as bright as the dinotte 300R.
But one can buy 6-7 of them for the price of the dinotte 300R!
Not sure where you're comming from regarding the "hassle" of charging a minewt for five hours
I've destroyed quite a few of these one-piece bike lights by removing them constantly. Charging on the bike is inconvenient for me.
