I’ve had my Garmin Varia RTL515 for years now. I bought the earlier version (RTL 510) which became an immediate “must have” on my rides. I’d never leave home without it.

Unfortunately the switch failed. Garmin determined that it was eligible for free replacement under warranty. The replacement seems to last better than the original did when it was first new.

I’ve always liked/ been a sucker for new technology and products. When the RTL510 was first introduced, I “had to” buy one.

Summarising how I feel about the Garmin radar with tail light - I just don’t ride without it, full stop, period.
