I purchased one unit a few weeks ago, the Innosilicon A11 Pro 2000 Mhs . It has worked out perfectly since it arrived. I was even provided extra support with clearance and delivery from Ketija who was very friendly and informative. She also responded go to me very quickly. I will now be making my second order very soon with this company and I have been offered extra discount for a larger purchase. It definitely helps with trying to get the fastest ROI on your purchase. If looking to purchase multiple units I would recommend contacting them first as they may be able to help you on the price For now this will be the only shop I’ll be buying from. Keep up the excellent work
