For 12v TV applications in a car, truck, RV, camper, etc., currently their are only TWO 7" (ATSC-changeover-ready) little TV's on the market: The HAIER brand, and the SUPERSONIC brand. The SUPERSONIC brand is FAR SUPERIOR to the HAIER brand. I have tried them both, and now own the SUPERSONIC brand. The HAIER brand is junk; it will not hold previously-scanned channels in memory. The minute you turn it OFF, all scanned channel memories are LOST. And, the TV must be "auto-scanned" all over again for local channels. Not good. And, HAIER even ADMITS to such in their little "Instruction Manual", where they warn: "NOTE: This TV is intended for CONTINUOUS operation only." I.e., it can't be turned OFF without losing all channels memory. Not good. I.e., the HAIER internal 9v (auxillary) battery must ALWAYS be installed so that "Standby" (and, channels memory) can be maintained. Not good. On the other hand, the SUPERSONIC brand RETAINS all memory, regardless as to turning it off; unplugging it from wall or 12v cigar lighter; removing the 9v "standby" battery (which is in a seperate unit, anyway). Take some good advice: don't buy the HAIER brand. It is JUNK. Have a nice day. (END)Get more detail about Haier HLT71 7-Inch Handheld LCD TV.
