Two R4 arrived yesterday in UK.
My impressions:
1- This thing is huge! I mean long and wide comparing to any S
2- It is way quieter than S3! You can potentially have it in the bedroom. My ones installed today in attic - can't hear a thing anywhere in the house
3- Hooked this morning to KANO.IS of course because:
- best overall historical luck
- best support from kano himself here on forum (almost 24/7)
- easy simple straight forward setup and web stats
- Status mobile App with notification for block find, miners speed
- and... o yeah first payment just came after little over 4hrs of mining!
