I bought an antena mast from them. I paid for the item and they delivered it on time, but they forgot to include the installation instructions as promised.
Before I bought the part, they were very responsive and answered every e-mail question I had immediately, but after the part delivered, I couldn't get them to answer the e-mail.
Luckily, I kept the FedEx or UPS delivery receipt, and it showed their address and phone number.
I had to call them to get them to fax over the instructions.
