Great Company, great service!

Extremely helpful and professional when I called. Patiently answered all my questions. Explained everything clearly. Very prompt shipping. Loved every thing about my experience with Radon Supplies. Highly recommend!

Order arrived unprotected in its packaging. In attempting a refund, company is refusing the full amount. They’ve stated that the order is undamaged. And I disagreed. They’re difficult to deal with, and I will never buy anything from them again. Right now, I have to pay for return shipping charges due to their errors NOT mine.
