Although I like the product, it sounds like a fine electric toothbrush, I dislike the name and subscription model.
Pros:

• A good toothbrush
• No need to remember to order new heads
• Up front cost low
  Cons:
• Over time this is an expensive product. about $9 USD per brush head, though I understand that this is to offset the no-upfront cost for the handle, the ongoing cost will add up.
  Summary: I will pass on this ongoing expense that seems too high.
