  • After Just wanted to say thanks for your service. It was first rate. We ordered a very simple part - 3.3V TTL to RS232, but your guy was very helpful and the order was delivered on time. It saved our ability to continue our testing. This was a classic case of a $10 part stopping a massive project. I will be recommending you to anyone that asks..
