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.

Well designed portable water flosser that's holding up so far
There are a number of such portable water flossers on Amazon, but this is one of the better ones IMO. The water pressure is adequate, with enough settings to allow you to ramp up (or keep using on a lower setting if desired). One nice feature is that the tank detaches easily and this makes filling under a tap easier than other units which don't have an easily detached tank. The tank shape is also a bit fatter so it's not too long along any one dimension. The tank capacity of 300 ml is adequate for a single use. The standard suite of flosser heads are included - flossing itself, peridontal, and one for braces. The tongue cleaner attachment is also there but I prefer to use a separate tongue cleaner tool. Charging is via USB-C and while the port isn't super water proof, there's no damage to the unit yet. Battery life is typical at about 20-30 days with twice a day usage.
