Review (3/5): Great until it dies.
There's a million of these identical head shavers on Amazon, all re-branded versions of the same thing, and they're all great for a few months until they just completely die and stop working.
This was the second shaver I purchased. This time under a different "brand" name as last time, and yes it was nicer and worked better than the previous one, but they always completely crap out after a while and it's a huge bummer. Worked great until it didn't work at all. If you're willing to pay $30 every 3 months for one of these, I suppose it's still cheaper than regular trips to the barber, but what a drag.
