They've performed as promised

Both my 40 and GO appeared to be shipped directly from a manufacturer in China. So, once ordered, it takes easily a week before shipment and a few days to get out of country. Once it hits the States, it seems to move along. Otherwise, I've had no issues, personally.

Shipped early! Box was a bit beat up but the packaging seemed to protect the product. This could have been FedEx.

Really good. Until now, there hasn't been a wonder-amp that made you wonder - how did they fit everything into this small thing? Well, software is the only correct answer, and PG is great at it. Now, calm down and go buy one.

My spark go arrive quickly and in excellent condition.
