Almost as good as my Ultreo. [SEP] The Ultreo was the best toothbrush I have ever had. But it had a bad failing, the rechargeable batteries in the handle were of poor quality and not replaceable. During Ultreo's short life, they sent me three replacement handles. When the company failed, i bought a bunch of replacement brushes. But the handle soon failed again. But I was able to sell my extra brushes on eBay for a very tidy sum. Next I bought the Sonicare, it was quite good. But when I got the new HydroClean brush heads, I realized they were almost as good as my old Ultreo. I feel this is quite a accomplishment as I loved my Ultreo. Ultreo is now back in business, but I will stick with my Sonicare and HydroClean brush heads.
