I would talk about the typical things like how little shaving rash I get after using this, but that's not why I'm writing this.
Being visually impaired, I rely on tech to help me though day to day life, so when I saw there was a one blade 360 with Bluetooth connectivity, I bought it instantly.
Firstly, the fact that the blades reveal an eject symbol when they're dull and need replacing is a godsend. I don't have to wonder if I'm shaving with a good blade.
Secondly, the app is amazing, as I can easily see my battery percentage, how many shaves are left until I need to charge, etc. The speed shave guide is good but I don't know if it's useful to me as of yet. The style guides don't accommodate for thinner moustaches and soul patches. It would be cool to have an app that tells you if you've missed any hair, and would be more useful than "style guides".
On the whole I use it more than my other shaver by a competitor which is a traditional foil shaver and has none of these features.
