I received the product, charged it up and the water feature did not work!
No, I would not recommend this to a friend.

Hello there - We are sorry that you are having this difficulty. The SF-04 model does need to be primed before first use. To prime the unit, fill the reservoir with warm water and replace it ÿrmly on the base. Point tip into the sink. Press the FLOSS button. Rotate pressure knob repeatedly between high and low until water flows. If you are still having difficulty, please reach out to us at 1-800-525-2774 or email smreviews@waterpik.com. Thank you.
I like that it is 2 machines in 1. It takes up a lot less space on my counter. The water flosser is stronger than my previous water flosser. It seems like it does a better job than my previous sonic toothbrush.
