Such a quality Antminer S19 Pro miner from Unigrade I bought and am pleased with my purchase!! The miner itself was exactly as described, with a decent storage temperature range. On top of that, Unigrade offers crypto payment methods which are very convenient and secure. Overall, I'm very satisfied with the service!
