I agree about the Premier medium blades on the Lister Star clippers. These blades last several clips (total) on my small, hairy horses with very dense coats, and can be sharpened repeatedly, so they’re a good value, IMO.
I was originally steered to these blades by an acquaintance who clipped professionally (who also suggested the Lister Stars); they are reputed to last far longer than the Lister blades (both by her, and by the shop which sharpens my blades that sells both brands - shop said 3 to 4 times longer).
IME, the Lister Stars are easy on my small hands, quiet, and don’t vibrate a lot – all qualities I can’t say for the Oster Clipmasters I’ve used (although the latter could certainly clip a yak). I clip several minutes, brush them off, soak the blades for a minute in a jar of something like the Andis Blade Care, wipe them off, oil them in all the recommended spots with the Wahl oil, and they’re ready to go after a very brief rest (which also gives my horses a momentary break).
My horses never object to the clipping, or behave as though the clippers are too warm, or the vibration is too much; they act as though it’s a relief to be clipped, and rid of all that heavy coat.
