Works well and includes replacement blades!
This razor is similar to the lower end models of so-called "name brand" rotary shavers.  It gives a pretty good shave and fits well in my hand. The 90 minute battery power is great (I haven't run out of power yet but that's the spec) and means one full charge prior to travel will do it.  Worst case it's a usb charge so typically I am set up for that on the road anyway. And I can see the remaining battery power on the display when I turn it on.  (You can lock the on/off button, btw, by pressing and holding it down for a few seconds.)  For the price it's a great razor to leave in my travel kit so I don't have to take a more expensive model with me. (Because who hasn't left something in a hotel room?)  The only negatives: it does not have a built-in sideburn trimmer which I really like. None of them are the greatest cutters but they are useful for a quick clean-up. And there's no travel bag but I have some bags from other devices that I'll co-opt for this one. One huge positive that helps to offset the negatives: it comes with a replacement cutter (with three rotary blades).  It's never clear with generic brands where one can buy replacement blades, and sometimes it's less expensive to just buy a new razor. They included the first replacement blades so in my mind that doubles the useful life of the product.  That's a great feature that every non-name brand razor manufacturer should include.  It truly differentiates this product from its many generic competitors.
