their customer service is useless ,collar 14mths old ,kept as backup,wasnt charging rang to get battery replaced was told nah ,you r gonna waste your money posting it to us and it would be better if you bought a new one ,,,aye right,,,pity there wasn't another source for collars which are made by barryvox,and those dsp sports bellman are selling for £250 plus postage can be sourced much cheaper..
