This valve turned a fairly new window unit a/c from useless junk to functioning fine. The valve is easy to install and allowed me to recharge the R410a on a window unit a/c. One note: the website says "Safe for use on the LOW SIDE of R410 systems" but the enclosed instructions say "Not for use with refrigerant 410A". I did use it on the low side and so far it is holding (~3 weeks). For the price, definitely worth a shot.

Great device for adding a service port.
I installed this on my dehumidifier. It allowed me to check the low side pressure and measure the superheat. The device installs easily and there are no leaks. A very low cost and high quality way to add a service port. I highly recommend it.
