The Coslus C20 & C41 are rechargeable and durable. Powerful and effective.. I really like them both have different setting for stronger, or lighter pressure and speed, andca massage mode. I am still going off the first initial charge.. thats very impressive. They get used around 3-6 times a day.and been running overca month. This is the second flosser I have purchased, only because I lost the charge port cover, unit still holds charge like new,and runs strong .its about a year old.
