^{i work away monday to thursday,i got a new lurcher(pup),great temprement,my brother keeps him when im away to work,to walk him ect as he has my dogs brother,been bloody hard work,they stay in his kennel when hes at work,they barked being young dogs to the extent neighbours complained,was so close to rehoming him........i spoke to a lad about these collars,with positive feed back purchased one,(last resort)problem solved,i can now carry on working and enjoying my lurchers,yes i agree could really do some damage in the wrong hands, but used correctly they are excellent pieces of kit, hes 19months now lying at my feet happy,far from nervous,only used collar a handfull of times,never use it now as its sorted my problems and the neighbours,great piece of kit}
