These are all fair questions and anyone should be able to find an answer before spending a considerable amount of money on a shaver.

Unsurprisingly, these changes don’t really have any noticeable effect on the shaving performance — we still have the same motor and foil/blades.

Linear Motor – The 14,000 CPM linear motor on the Arc 5 boasts a massive power output of 70,000 cross-cutting actions per minute. This is one of the most powerful shavers compared to its competitors. For example, you’ll sometimes find there’s a significant price difference between the ES-LV65 and ES-LV67 models. The typical AN/ARC-5 three-receiver, two-transmitter installation reflects system capabilities that are quite sophisticated compared to the earlier systems, allowing VHF homing, four channel VHF-AM communications, and one channel MF/HF-AM communications. All unnecessary controls have been eliminated to simplify operation of this more capable system.Short-range radio systems designed for aircraft-to-aircraft communication, known as command sets subdivided into a multitude of bands. Tip: the revision B shavers use B instead of A for the model names: for example, ES-LV9B vs ES-LV9A. This naming scheme will continue with future revisions, but it won’t always be consistent. And while most models are specifically marked as suitable for wet/dry use (ie with shaving cream or in the shower), there are some that are only washable (as in you can clean them with water), but can only be used dry.
