Juan has been wonderful to deal with.
I've purchased S1's from him and an S3 - #1235.
My S3 has been sitting in the Chinese clearing house for close to 2 weeks, but Juan is looking into it.
He is a reseller, not the shipper.
I was abit upset when I missed ordering S3s from him in the first few batches but was able to get in on batch 5. When I ordered my batch 5 from him, I got a confirmation email right away after paying by btc thru BitPay.
I managed to get in on the earlier batches by buying 2 S3s from a competitor. I had to pay more then i would have been charged by Juan.
The S3s are very nice machines. I like them even better than the S1s. They run cooler despite the higher GHS/watt. My two are often higher than the 441 GHS....but I am using a single 600 watt PSU for each one.
