I have been using oneminers for a couple of months now. They provide clear and detailed information about their services and have a transparent fee structure. Plus, their customer support is responsive and helpful. Their platform is reliable based from my experience, they are true to their fees (no hidden fees) They have a very seamless dashboard for all the mining details and information you need. I'll update this if in case something bad happened in my mining operations with them. So far oneminers is a reliable partner. I saw them participating in the recent BTC prague event as well.
