I also have Waterpik Evolution countertop and the pressure pulsation of Evolution at number 6 on a pressure pulsation dial (1 to 10) is stronger than this cordless water flosser on high setting. I wish the Waterpik can add an optional cord to plug the water flosser to the wall so I can do water flossing with more pulsation power. Anyway I plan to use the cordless water flosser for travel as well as backup in case the other water flosser breaks or when there's a power outage. I used to own Waterpik Ultra long ago. The first one broke after few months so I got another one and it also broke. I also bought cordless water flosser of a different brand and it also broke. It seems water flossers easily break. I need the water flosser anyhow as I have gum issues and recession (gum receding) and this water flosser would help. My dentist encouraged me to get one. Doing water flossing makes my mouth feel fresh and clean and I hope I can keep using it and they don't break.
Disappointed in the low pressure. Big and clunky to hold. It does provide precise cleaning
No, I would not recommend this to a friend.

This gets the job done well. I’m really enjoying the attachment with the mini brush on it to help keep crowns clean in between. It holds a lot of charge, I only have to recharge it every few weeks. I keep it tucked on my counter next to my kitchen sink so I can use it after I eat. The blue color is a fun option, too.
