We purchased this to use with Wheel of Fortune and Jeopardy. As many other reviewers have stated, this item is completely worthless for this purpose. We have tried various settings, moving of objects, eliminating any possible sound conflicts, moving our furniture and people placement in the room, screaming and soft-talking...NOTHING results in this item functioning, even remotely, to its purpose. I believe this item is not a viable product. It should never have been put on the market. Do not buy this product...save yourself the headache.
