Mine are in getting fixed right now. The worst part is that the adhesive appears to be coming off in places (it could be the track though). Not sure if it's due to heat or poor surface preparation. Some of the lights work sometimes, sometimes they don't. These LEDs look great when everything is working right, but based on what I've read on the forum, it appears to be a warranty issue for many owners. Most company's track their warranty issues and either have the vendor resolve the root cause of the issues or they move to a different vendor. Not sure where Heartland is with these, but I'll bet it's making their radar. Hopefully, they have had time to address the problem with the new LED replacements they are using during warranty repairs (sounds like it based on what Jeff said).
