We ride 3 to 4 times a week early morning (around 330 am) for 20-30 miles and lights work awesome ! Front light quit one day and in 2 days had anew one at my front door, great warranty and customer service !!!
Auto drivers visibly respond to the lights which are quite brite, but not too bright for my riding buddies.
The mount release lever should be moved to the front of the mount because I can brush it with my leg at times which releases the lock.
Picked this pair up for my partner. Great deal, great lights. I almost switched for them when they arrived but decided to be a good gift giver. They are bright with adequate battery life.
