I bought this device and use a brand new sure 52 with it. The noise and feedback I received with this device was horrible - I might have a bad unit. When I called customer service, a real person answered right away and offered to expedite getting me a new unit. (Very cool and is why I gave them 3 stars for now) I'll see how that process goes and update my review.
