I use these to replace the filters on our air quality monitor. They have done a good job and are just what we needed at half the price that is typically charged. Thanks. :-)

Good Review

My cat absolutely loves this toy. He destroys anything we buy him, but he has not managed to destroy this.. yet. I've seen him play for an hour with it each time I put the ball in his hand. Only issue was that one of the plastic attachments broke off, so now all the balls come out. If they can fix that, you would have a great product. :)

Ex Output:
Good Review

Bought this product with the intention of saving space. The unit I received would not power on. Had to send it back. Amazon worked well on sending me another replacement, and so far haven't had any issues yet. UPDATE: Second Unit DOA as well. Same problem. Power light just flashes for a second then shuts down. No more OCZ products in my house. Returned it and bought an Icy Dock instead. It is also much better than this. Avoid if it's going behind your entertainment center.
