Review on FJC 2850 Digital Scale by Todd Atherton

Good scale for AC operation EXCEPT that time runs out and shuts off pretty quickly so you have to be really careful or you won't know how much Freon you've recovered. Also, the last measurement isn't saved, so you'll need to weigh an empty refill jar and write that number on the jar in case you forget it, so you know you've restored/charged it.
