I had a very pleasant experience too with Lezyne support. I have a pair of the Smart Connect lights (front and rear) on my e-bike. We had a crash and the rubber button on top to turn the headlight on popped off, and we lost it in the mayhem. I contacted Lezyne support via email (sent them a photo of the headlight) and they shipped the replacement to me the very next day. They did not charge me (I was willing to pay). While it might be only 10 cents, their proactive and prompt service made me a customer for life.
