I bought this light in October 2022 and use it 2x-3x a week. It's an awesome little light and was very effective during my dark (and also, for the record, cold) morning rides in New England. In April the USB tab broke off, but I wasn't diligent about cleaning it when it got hard to take in and out.
After confirming it was under warranty, Light & Motion replaced it in about a week. Really superb customer service.
I also own an L&M headlight (VS1000) that I recommend.
