I'm sorry to be a downer, but I didn't have the best experience working with GREATMAG. Although the website is attractive, the absence of product information made me want to shop at other vendors. Let's also discuss about the checkout procedure, which was like attempting to pry apart two magnetic forces. Sadly, their products weren't good, but their customer service was only fair. I apologize to GREATMAG, but I won't be lingering.
