Smwrote a review of NiteRider Solas 250 Tail Light on April 1, 2019
Familiarity: I've used it several times
The actual light part of it works as advertised. But it has lots of issues. It doesn't stay in position very well, sometimes it will shift and I'll find at the end of my ride it's now pointing down. Not too helpful to have a rear light facing down. The rubber cover over the charging port is difficult to put back in so I'm never sure if it's covering it and preventing water from getting in. There doesn't seem to be anything in the manual about the charging light indicator. Sometimes I plug it in and there's no light so I'm not sure if it's charging or not. Sometimes after a few hours the light will turn bright red. Then after that it will turn blue. I think that means it's fully charged. But not sure. All in all I wouldn't buy it again.
