I would like to share my positive experience with Bitmain.

I ordered 2x Antminer C1 with cooling kits excluded. Right after my bitcoin transaction got included to a block I received a confirmation e-mail that stated my order was paid.

The delivery of batch 3 of C1 was started on Nov 17th. I placed my order in the evening of 16th. As there was probably a lot of other orders on the line I felt good when they shipped my order at 19th. At 24th the package arrived my door.

Bitmain used UPS Saver delivery. This is the fastest method that UPS has but I wonder how they can promise 48 h delivery for orders. On my shipment it took up to 48 h for the package to get only from Koeln, Germany to Stockholm-Arlanda, Sweden. Even without the delay between Germany and Sweden it would have taken three days to ship.

The time from payment to package arriving was six days. If the package was delivered in 48 hours instead I would have mined 0.1 BTC more. That's about 3 % of total bitcoins these miners will ever produce. They should give coupons for compensation.

However, right now my miners are happily hashing at 1.01 TH each. I have to say that I still regard Bitmain as the best vendor there is.
