There brushes are AMAZING!! Definitely worth every penny & more! They have changed our grooming life in this house and I would totally recommend them 110%, you WONT be dissapointed. I have never seen brushes like these. This is what we have:
http://www.chrissystems.com/slickers.htm Mark II slicker, I used on Rocky & the maltese, Haley I dont seem to use it that much and if youre growing their coat I wouldnt recommend a slicker. All of mine have short hair and its great for mats etc.
http://www.chrissystems.com/slickers.htm We have the 20 mm obong brush that is awesome, the pins do not scratch and its the best brush, I definitely think the 27mm is too big for any dog under 10 lbs, but that is just me. I use this on all 3 of mine, a lot of ppl I know have the gold series, I got it for a friend for xmas who has her yorkies in long coats and she loves it also.
http://www.chrissystems.com/combs.htm The combs are a must have, for now we have the buttercomb #000 and its the best, I love both sides and used both sides. Eventually I will get a few more combs.
There brushes are awesome IMO and I have never known anyone to be dissapointed. I havent used the silk spirits, but have heard mixed reviews, Some people like it and some dont. Just like with shampoo & conditioner, to each his own and different hair textures will produce different results.
