We tried one other collar and it broke which is why we got this one. So far it has been working really well. The battery for both the collar and the remote seem to last a lot longer. The only thing I wish was different was the charger. It’s nice to be able to charge both the remote and the collar at the same time but if I was to ever lose the charger, I wouldn’t be able to charge the collar. The charger is very specific.
