Base isnt a charger, But otherwise its decent.
The overall quality of this product is high. It worked and funcioned as expected. My toddler hated it. He couldnt deal with the vibration even on the toddler steeing. It has 2 settings for different age ranges but you have to go through them every time you turn it on. This would have been better as a selector switch somewhere else that remained in place. The base is NOT A CHARGER. that was very dissapointing. Not only is the base NOT a charger, you cant even plug the toothbrush in and then let it sit in the charger. The should have just made the base...the charger. Plug that in and leave it and that way the tooth brush stays charged all the time. Overall other than the base being a dissapointment this isnt a terrible toothbrush. If your child is ok with the vibration they will probably love this.

Works well has plenty of pressure.
It is a great device, a bit awkward to use over a bowl sink, but with some minor adjustment of the nozzle, it works well. It appears to be as effective as most water picks and I like not having to fool with a hose, that can break.

Needed replacement, 2nd one works OK
The first one I received had a broken latching mechanism. Not a shipping issue, as the box was fine, it just wouldn't latch the attachments because the mechanism wouldn't come all the way out. After getting a replacement the 2nd one worked better. It has 3 settings for soft, normal, and pulse. For me, the normal put out the best force for clearing out bits. After washing with it for about 30 seconds though I still don't feel it cleans we well as real floss, or even a waterpik, but it does help after brushing. I will add it to my routine as it does help flush out some things, but it won't be replacing my flossing. It is sort of portable, in that can be packed away and holds a charge, but it's still pretty large and takes up a good amount of space in a toiletry bag. It's not bad, but not really outstanding either.

I like this better than my name brand unit
🔵 Features: The water pick boasts a generously sized reservoir, which is a standout feature. It also comes with a convenient USB charger, offers 3 speed settings (normal, soft, and pulse), and features quick and easy detachable heads. 🔵 Power: In terms of power, comparing it to my current unit revealed no noticeable differences in pressure or volume to the naked eye. Both units effortlessly deliver a stream of water up to 12 feet. 🔵 Heads: The water pick includes a plethora of heads, more than most people would likely need. Personally, I would have preferred a lifetime supply of the simple angled head picks, but the variety provided caters to all preferences. 🔵 Overall: After using it for a few days, I found that it performs admirably. When placed side by side with my old unit, I consistently reach for the 7AM2M unit, primarily due to its larger reservoir. In all other aspects, I find them comparable, and I wholeheartedly recommend this water pick to others.
