You have to get one in your hand to understand how nice the hockey puck is.
I signed up as a dealer since the last post and have about 50 in the field now. I have had two issues thus far, one with a collar I owned personally and one with a client collar. Both were replaced immediately FOC and a return label sent.
Service has been great so far with any issues and ordering has been very easy.
Not sure how many out of 100 we'll have issues with yet but I doubt it will be 4. The product is very well made.
