I've gone through 30 years of good and bad lights. This one is good. The strap and rubber grippers hold it on well and won't scratch anything. Strap hasn't degraded over 3 years. (I might have the "90" version actually. Not sure.) Battery still going fine. Switch is more tactile than most and possible with light gloves. Blink modes are the usual, fine. Daytime mode is good and bright.
