Checked out Unigrade and gave them a try as well. Bought from many stores before, and I like to test the sites. Here I bought the Bitcoin Miner S19 XP Hyd. It's a great piece of hardware for mining crypto, no doubt, but while the product was one of the lower prices I found, with shipping it turns out to be slightly more expensive than other stores. Yet the quality of the hardware on this miner is outstanding. Great buy.See full review
