We have improved now all the shippings. Unfortunately, the shipping time does not depends on us.  Now we offer a true 24h shipping service as we have UPS shipping, but the price is higher.
All the support related with the 1 chip board is on this thread. Just ask your specific question and provide as much information as you can, like pictures or how did you proceed with the connections. For instance, saying "the chain doesn't work" does not help too much.

We provide the specific version of the software we use. It may be an old version, but we get the best performance with it. We have also posted some alternative and even newer software like chainminer.

The performance of the board depends mainly on the core voltage and the software setups. 2.5 Ghps should be a reasonable performance for this boards. Most users reported a good performance.

We understand your complaint. Just post as much information as you can so we can help you.

I thought this was solved. We send you a 5V 1A because for 1 board it's enough power. The board takes less than 2W and the power supply we send you is 5W.  Should work fine.
