I now have 2 of these clippers - my wife uses the old one to trim the dog - so she bought me another for myself (but I still use both). What I like:_ The batter lasts forever Easy to clean Great, snag free results easy to use great results! Please let me know if you ever plan to discontinue these - I will buy a few more to last the next 50 yrs :) Only feedback is that on the newer model the blade has sharper points which requires more care. I usually just use the cartridge from the old one which works on both.
