It has 3 speeds and the max or 3 is very weak in terms of power. Especially against the one it replaced. Pretty disappointed.
No, I would not recommend this to a friend.

The reservoir leaks. If there is water in the reservoir and you stand it on the counter it leaks. The reservoir is also nearly impossible to pull off the waterpik.

Hello LB124 - We're sorry to hear about the reservoir leak. The unit isn't designed to hold water, so leaving it inside after flossing can cause it to leak. If you're facing a different issue, please let us know by calling 1-800-525-2774 or emailing smreviews@waterpik.com.
Leaky reservoir, not happy. Hopefully new reservoir being sent to me will hold up beyond the 2 weeks of use I had with this one!

Sometimes it runs out of water before I’m finished . I use it every day after each of my three meals and I've recommended it to all my children and grandchildren . find it's very helpful . However I need to charge it every three or four days. And that surprises me.

Hello Roger 37 - Thank you for your feedback and for recommending the WP-580 to your children and grandchildren. We're glad to hear you find it helpful. Regarding the battery life, a full charge is expected to last 3-4 weeks when used once daily. Since you're using the unit three times per day after meals, more frequent charging is normal and expected. If you have any concerns, please contact us at 1-800-525-2774 or email smreviews@waterpik.com.
