I have: bought a Sony A7II - excellent condition, came with a Ravpower charger and two spare batteries. Only flaw (as was pointed out in description) was a torn eyepiece rubber. I have also bought a couple of m-4/3 lenses (Panasonic 14mm f/2.5, 20mm f/1.7 mk II) and both were optically flawless. If anything I would say their descriptions are on the conservative side of accurate. Prices are good and they frequently offer discounts.
YMMV, of course, but I would have no qualms about buying from them again.
