I bought a new WaterPik and it had where I could purchase toothbrush heads. I tried to order on line only to find out that the round ones would not fit on my new WaterPik. They should be interchangeable! I am used to having a round brush not the regular toothbrush shape and was willing to buy the extra ones with round heads. I like the use of it and would recommend it but now I have a WaterPik that I dislike due to the toothbrush head.
No, I would not recommend this to a friend.

We are sorry that you are unhappy with the product. The reason that the round toothbrush heads do not fit this toothbrush is because this toothbrush has sonic technology and the round toothbrush head is for the oscillating technology. They each use completely different technology. If you would like more information, please contact customer service at 1-800-525-2774 Monday through Friday from 7:00am to 5:00pm Mountain time.
Compact Size . All in one. I switched from a sonicare toothbrush and a seperate waterpik hand held water flosser. I was concerned about the Quality of a sonic toothbrush that was not made by Sonicare. This unit provides sterling results .
