Many people do use them with good success. However, it's a poor choice for gauges, despite being an OEM part (my opinion from an electrical/electronics perspective only - nothing more - take it for what it's worth (exactly what you paid for it)). The chopper or pulsed signal cannot provide the most accurate reading. Accurate enough? Probably. But they're $30 (unless you scrounge one in a junkyard) and the CVRs are pennies. New technology. Sometimes it is better.
