I did a lot of research as I had been buying cheaper clippers for hime grooming and while they did the job the didnt last long so this time I was looking for professional clippers that werent too expensive with a good reputation and longevity. I bought the cordless pro max and used it last week. I must say they slid through my springers coat like butter left no cut lines and was done in 20 mins. I cant wait for his hair to grow so I can use them again. Would highly recommend masterclip but will have to see how long they last for 10 out of 10 ratings
