Review (2/5): a marketing campaign masquerading as a personal grooming product
The rotary trimmer cuts literally nothing, it's less useful than the $10 throwaway ones you can get at CVS. The other trimmer is no better than the cheap drugstore ones either. The guard is flimsy plastic and not really usefully adjustable, you can't really disassemble it easily for cleaning, you need a USB cable to charge it, and the on/off switch is easy to turn on accidentally in a travel bag unless you do some combination of clicks to lock it and unlock it, where it could have just used a slider switch like every other one.
