I received this product in exchange for my unbiased opinion.
The Good: Wow! This toothbrush leaves my teeth so clean! Even several hours after brushing, my teeth still feel as clean and smooth as right after a professional dental cleaning and polishing. My gums feel healthier, too.
I think the ultrasonic waves clean between my teeth better than other electric toothbrushes I`ve used. I like that the brush handle is lighter weight and less bulky than older electric toothbrushes and that it comes with a travel case. I could actually see myself bringing it on a trip. The travel case has room to hold 2 brush heads. For use at home, 1 charge lasts 2 full weeks, so it takes up minimal counter space.
The toothbrush is very easy to assemble, comes pre-charged, and has a very compact charging base.
The Bad: I was surprised to read in the manual that a different brush head is recommended for each of the toothbrushes 3 brushing modes (clean, white, and gum care). This made me feel like I could only use the white brushing mode, which is a 2.5 minute brushing cycle. One of the large buttons on the toothbrush switches between brushing modes, but I always kept it on white mode as the brush came with a W brush head (despite the manual recommending a newer W2 brush head).
The other settings were less intuitive to use and require referring to the manual each time a change is needed. To turn functions such as EasyStart, Brush Head Replacement Reminder, or Pressure Sensor on and off, you hold down the start button until it beeps a certain number of times, and then release the button. A triple tone of low-medium-high or high-medium-low means the feature has been activated or deactivated. You have to check the manual to see which feature is after 2 beeps, after 3 beeps, etc. and which set of 3 tones indicates activated vs. deactivated. There`s no visual indicator on the brush for which of these features are turned on.
The Ugly: The toothbrush is very loud and the vibrations are so strong that toothpaste flew out of my mouth and only my bathroom mirror when I opened my mouth slightly to reposition the brush to reach certain parts of my mouth. It was loud enough that I couldn`t hear someone talking right next to me.
The toothbrush also has 4 very bright white lights on the toothbrush that turn on as soon as you pick up the toothbrush and stay on throughout use. I may cover these with tape as I find that uncomfortably bright, especially right before bed.
Other thoughts: It would be nice if the toothbrush came with something for storing more brush heads on the bathroom counter. It would be ideal to purchase 3 different brush heads to be able to use the 3 brushing modes, and some households might want more than 1 person to share the same toothbrush base but with their own brush heads. Another electric toothbrush I`ve used came with a countertop case that holds 4 brush heads and has an easy way to color code different people`s brush heads. Something like that would be an improvement for this product. The travel case is bulky for just storing 2 brush heads--it`s designed for when you need to store the tooth brush base and the charger, too.
The bottom line for me is that I`ll probably continue to use this toothbrush once a day, but use a different one that`s quieter, less messy, and doesn`t have bright lights at other times. The quality and outcome are great, but it would benefit from some changes to make it more user-friendly.
