I've always bought Seresto collars and never had a problem. This collar worked well. for 3 of my 4 indoor/outdoor cats. The one who spends most of the time outside showed up full of ticks anyway. So I just ordered 4 new Seresto collars and changed them all. Maybe it was just a bad collar, but I didn't want to risk it.
