Decided to invest in some professional clippers because of the ever increasing cost of the groomer. Hopefully we will now be able to reduce the number of visits to the groomer. I bought the ex-demonstration set, which looks like new and comes in a very sturdy carry case. It's still a learning curve for me as I've not used clippers before but have watched numerous you tube videos and am getting more confident. My dog had a bad experience at the first groomer we took him to and is very nervous about being groomed, therefore we have to take it slowly and stop when he's had enough. So long as he's matt free I'm really not bothered if he's completely even all over - it adds to his character! I would definitely recommend these clippers.
