Almost a year ago, I purchased a display sign from Signtronix. At first, I was very pleased with the sign, then after 3 months, the time and temperature display was showing incorrect readings. I have been dealing with Signtronix for over 6 months now, they have sent replacement parts, and every time I have to pay for the service charge to have replacement parts removed and installed. I feel I have a defective sign, and I have spent several hundreds of dollars in just service charges to work on the defective sign.
