I must say, that Daiva said true. Electrical collar is absolutelly normally using by IPO top training (same like needle collar and string collar). In Germany too !!!
Electrical collar is very good training tool, but only for very specific using and using only under supervision of good experienced trainer. Is stupid to say, that electrical or needle collar are bad. With knife you can killing, but cutting bread as well. Every tool is good, if is correct use.
