I got the Interplak electric toothbrush at Target, it's under $20.00 and has a small round circulating brush, I feel like I can do a much better job with it than the manual toothbrush. I haven't been using it that long, but it's quiet and Joey seems to cooperate better than with the manual. He also didn't like the Petzlife, but I can spray it on fast.
