I was told by a gentleman that sells and sharpens scisssors and clipper blades, that the only difference that he sees in the two is that a lot of people claim that the original red clippers are a little easier to hold in your hand. I really don't know. I do have the red ones and like them a lot.
the purple and black and the green and black are supposed to have a grippy thing on them to make them easier to hold( its almost rubbery) but when you are grooming hair gets on it and makes them more slippery.
its wierd go for the red ones, they are great
I ordered the Andis AGC-2 speed (dark red in color) to trim my Standard Poodle I who just rescued recently. Just clippered him the first time yesterday and these clippers could hardly go through his dense curly hair. I brushed him first, like I read I should do, but still had a difficult time. I didn't want t shave him too short so I used a 3 3/4 blade and a 7FC. Any suggestions? Thanks.
