“Fabulous personalized customer service! They didn't just sell me a product. They gave me design suggestions for my project and helped me pick the right product to work best for it. This is the kind of "go the extra mile" customer service that is disappearing in an Amazon world.”

“They take the time to find out what your needs and expectations are and will far exceed them. They don’t have used car salesmen vibes!”

“Calling TRU Off Grid and speaking to Jack (May 12 am) was one of the most rewarding experiences in customer service I have ever had! … The order was shipped about 2pm Monday May 12 and we received it ( we live in the "sticks" in Lanark Highlands Ontario) about 2pm Tuesday May 13!!!!”
