This product has been amazing!

Product stopped working after only a month or two.

This product doesn't enhance signal like it is a advertised to do.

This product was a complete scam

I would recommend this product and would purchase again.

Wonderful product.

Product works well, but the transmitter and antenna need to be separated pretty far to prevent the transmitter flashing errors due to oscillation.

Update - Dead T-Mobile registration links still found in setup guides online from several sources

To bad t-Mobile support could not provide it over the phone.
