The product is good quality, made from excellent materials. The accessories—I mean, the case in particular—could have been a little more thoughtful. I'm not crazy about the bristles on the toothbrush, but I don't understand the bristles' arrangement, and for the same reason, I find them a bit awkwardly ergonomic. But these are just technical considerations, as I'm a dentist specializing in periodontology. Overall, it's a very practical device given its size, ideal for traveling but also very elegant for keeping in the bathroom. The packaging is also thoughtful. We could work together on the above-mentioned aspects.
