Coby CTV555 5" Color TV
works best with CATV
As a portable color TV this product would rate a 2. No battery power. Only AC/DC, including the auto adapter. It picks up 4 or 5 UHF channels but not any VHF in my large city, though with large amounts of static.  On the auto adapter outside it picks up 2 channels in my city, so the built in antenna is a weakling. The AM-FM radio works well. Sound is adequate for my workshop. However, I'll give it a three because as a stationary TV in my workshop, hooked directly to cable tv, it picks up 20 something cable channels (out of at least 75), with a good picture. Oddly enough the digital tuner picks up at least 5 channels that are not available in my cable package on my other TVs, and the channels are established in a different order from the full cable package on the regular TVs! Go figure. This must be why the product is not advertised anywhere online as cable ready, though the user manual indicates that it is fully cable ready -- probably in China. So don't buy this as a portable TV; maybe for the kitchen or workshop.
