Pros: 1) Wireless! 2) No sensitivity, compact storage.
Cons: 1) The case doesn’t actually charge the mouthpiece unless it is plugged in. There have been several times when I have gone to use the kit, but the mouthpiece battery had half or no charge because I forgot to plug it in after using it the day before.
Also, it would be great if the larger sized wands could fit inside. Currently, only the standard sized wands do.
Overall, I am happy with the convenience and results. This is the first whitening system I have used that gives zero sensitivity issues and actually whitens.
