I have used Match x M2 pro miners for sale. The miners are north american version (Canada). The miners work great. No issues at all. These are great low power miners that mine mxc, crankk token, dhx, polkadot and BTC with as low as a bulb electricity consumption, no noise and no heat at all. This is a great deal given the price of tokens is low so the miners can be refilled cheaply. So far, approximately 35000 tokens have been mined on these miners. Any questions feel free to ask.
