Reading some of the previous reviews on GRP, struck me as eerily similar to my experience with them. They sent me a thermostat that literally blew up upon installation. When i tried to return it, they asked me to take pictures of the item, shipping lables, etc. and send it to them. When i questioned this arduous return policy, the agent, Felicity promptly hung up on me. This seems to be a pattern based on other reviews that i have since read about this company. When i filed a complaint with paypal for a refund, they challenged my claim. This is an unscrupulous company that will not return your money. Beware when buying anything from this company.
