Gave this the the AC service guy and he installed to fix a leak.
Product stopped the leak and seems to work. Purchase this product and gave it to the AC service guy to install with more Freon been working for 4 weeks now great leak free. Just make sure you don’t put too much of this in your unit. If you put too much in your unit can do more harm than good only install to match the ton size of your unit.

I worked great.
I have put this in several customer’s units and seems to work great. One system had leak that we could not find and was adding 1 pound of 410 every 2 months. Haven’t had to put Freon in for over a year so far. I can’t say that it will always work but so far it has for my customers.

Didn't work.
Should have been nice to know the minimum refrigerant size before I bought it. Wasn't easy only doing half a tube. To me it seems like a waste of money.

The smell was awful.
Do not use on a dehumidifier. It smells awful. After putting Nu-Calgon in the dehumidifier and charging the unit, the charge was gone in less than 24 hours.
