Having had a Nano3 for just over a year now I have so fat had a new PSU, A cooling fan for the PSU and a replacement Nano3 miner. Now, just over a few weeks after warranty expires, the replacement Nano3 is dead again. Not really impressed with the build on these, they don’t seem to have been built to last for any real length of time. Not really worried about ROI (only lottery mining BTC) but would expect the unit to be designed and built to at least perform the task to which it was advertised. I don’t think the PSU was up to the task and the internal construction of the Nano is a little suspect. Another project (and supplier) that I will not be returning to. Anyone else had a similar experience ?
