I have found the customer support excellent. I had technical issues getting set up but petTracer helped get me online and tracking my cat in no time. The collar looks great, and doesn't seem to bother a cat who has not worn anything for the first two years of her life. Moving to a new location prompted my purchase. It is interesting to find out where my cat travels to and gives great peace of mind. I loved the fact it had a radio search function also, although I cant quite get that working well, but Im sure if I got in touch petTracer would explain what I am probably doing wrong!
