Very nice water flosser & sonic toothbrush set
This is a very nice set of a portable water flosser and a basic sonic toothbrush. They are sturdy and appear to be well made. They are relatively compact and easy to pack to travel. They work well and do a pretty decent job of flossing and cleaning my teeth and gum, leaving my mouth feeling fresh and clean.
The water flosser is a one-piece design with a detachable water tank. It isn't overly bulky but rather comfortable to hold. It comes with 4 interchangeable nozzle tips (2 standard, 1 orthodontic & 1 tongue cleaner). It has 4 cleaning modes including a custom mode in which you can manually adjust the water jet pressure (10 intensity levels). It is pretty easy to use and does a decent job of removing food particles from between the teeth and along the gum line. Charging is done via a special USB cable (provided).
The sonic toothbrush is basic and functional. It brushes well and leaves my teeth feeling fresh and clean. It has the usual 2-minute timer and 30-second interval reminder. The 3 basic cleaning modes are adequate for my needs. It comes with 4 replacement brush heads, which is essentially a 1-year supply. It is rechargeable via USB-C (charging cable provided).
All in all, I'm pretty pleased with this water flosser and sonic toothbrush. They work well for what they are designed to do. Comfortable to hold and easy to use. The material and build quality seems decent as well. I think it is a good investment for everyday dental care. They get the job done.

Perfect For Those Upgrading From Manual Cleansing
Whether you just need to replace your old electric systems or you are moving on up to the electric age, this is a good set to go with. Also makes for a nice gift.
You get both a sonic toothbrush and an oral flosser. Once you take that step, you'll never go back. So much more thorough cleansing all around. The toothbrush is nice and powerful at 40,000 VPM. That's pretty powerful and gives you a much deeper cleansing. Personally, I wouldn't go any lower than that unless you have really sensitive gums. Of course, you can adjust intensities with this, so you'll be fine either way.
The oral flosser is good and will get what your toothbrush misses. That's not a reflection on this particular toothbrush, but on toothbrushes of any kind as a whole. Does a great job at removing all sorts of stuff lodged between your teeth. Easy to use and you won't have a water line getting in your way. I would highly suggest that you pour a little bit of mouthwash in with your flosser for an even more effective cleansing.
You get several replacement heads for your toothbrush and several different tips for the flosser. Enough that you'll have a very clean mouth for a good, long time.
