[This review was collected as part of a promotion.] I'm used to using an electric toothbrush with more features included and so found using this toothbrush a little bit frustrating, especially the fact that it doesn't have any timer included to keep track of the 2 min recommended brushing time. I also found the toothbrush a bit fast/strong the first time I used it and ended up with toothpaste sprayed all over my face. It seems to have improved slightly after using it a few times, but it would be great to have an option to adjust the speed. I do however like the small size and think it will be great for travelling and really like the carry case (just a shame it doesn't fit the charger in as well!). The only other thing I have found challenging is when I want to do a quick in between brush...not so easy with an electric toothbrush and also it seems to leek down the handle when I've gone to use it again.
