Whistler was very good in replying to me about a problem I was having with my TRX-1. They determined I needed to send it in. Cost was $120 and you have to pay with a cashier's check or money order. Same good email experience with a Whistler inspection camera that had problems. It is going to cost $75 to repair. I learned an expensive lesson. Thought I could save money if I shipped them together. Do not let UPS package you stuff. That is not Whistler's fault , but the shipping bill was way too high. The package should arrive today and I hope they can turn them around quickly.
