Having problems with mine .. contacted customer svc. and haven't heard back yet (the weekend so I am not surprised).
Keeps getting "stuck" on, or won't turn on ... took it apart, connections are good, etc.... anyone else using these lights. I liked to for the 24 hours (one evening) I did have it , an, I went and ordered two more for my other collars... now this one is having problems...!
Any feedback if you use them would be cool - likes or issues, thanks!
