Query: ZDCTV1Z Digital HDTV Antenna

While this product may indeed pull in a week signal, any benefits are outweighed by the flimsy construction. The one I purchased didn't work at all until took a closer look and found that not one, but two solder points were broken and had to be re-soldered. There was obviously no QA at all done after assembly.
