The clippers go through a double coat and a good selection of blades although I think they are quite a difficult shape to handle as I am used to barber clippers that are much more ergonomic and I find the on off button is in a difficult place to actually use. They also get hot really quickly and I only have a small dog.They also sound as if they are struggling power wise but they still carry on ok. Good that the company advise and sell the appropriate size blades for each breed though , that is a good help. Overall they are ok but was slightly disappointed on the ease of use, but I am a barber and I am used to light weight smaller and quieter clippers that are cordless., so maybe my judgment is biased.
