It's good but uncomfortable.
July 11, 2018
I like this OneBlade. I've only used it for facial hair and it does the job very well. The head has a trimming mechanism that is similar to those electric trimmers you would be using for your hair (ie there are guide fins where, inside, a blade rocks from side to side to cut the hair). For something of this category, OneBlade still manages a pretty close shave and leaves the skin reasonably smooth.
This particular model is fitted with a Li-Ion battery which, unlike the Ni-MH one found in the cheaper QP2520 model, lasts a bit longer and charges many times faster. Also, Li-Ion batteries are more durable and do not suffer from things like memory effect. Take this model instead just for the battery.
As far as comfort goes, this doesn't fully live to the promises. Yes there is minimal contact between the blades and the skin, but mine gets very irritated, especially under my jaw, at the neck. If you're looking to buy OneBlade solely for comfort, you will be disappointed. Otherwise, practically speaking, this is a good razor.
