S19j Pros excellent machines and… S19j Pros excellent machines and delivery. Checked it over, plug it in, quick setup and was mining in minutes. Power consumption and hash rate consistent with a daily average hash rate as advertised on BitHay.

Wow! Happy with the order. Wow! So happy with my order. Firstly I would like to thank the whole team at Bithay for helping me set up my ASIC. I was new to this and they really supported me through the whole process. My Goldshell Kadena miner is hashing away and performing better then I could have ever expected. Thank you so much for your service

Good Price, Great product and Quick emails. By far the best communication from any ASIC mining company. I Bought an S19j 104th, the dispatch time was fast and the Bitmain warranty is still 349 days when it arrived. They were able to answer all my questions and delivered my miner exactly to the day when they said they would. Could not have been happier to have gone with Bithay. Very Trustworthy Seller!

With this company all I get is delays With this company all I get is delays. I never receive my miners on Time always 1 month and up to 3 months late. I pay extra, almost $200 for shipping for a miner that supposed to arrive in November yet 2 months later I get it. If I wanted to wait the extra 2 months I would have ordered the later batch and paid a cheaper price I have had 3 power supplies that where not working and when I contact them they say send it to bitmain yet bitmain wont cover it because it was clearly used and did not come from bitmain and im told i have to cover the cost if I wanted fix. Out of all the orders I’ve made only 1 shipment i never received I contacted Bithay they said they will look into it and when DHL confirms to me I never got it and i send proof to bithay they will not respond and ignore me. They will not take responsibility for anything and always blame someone else and never help you if there's any issues.
