Leak Shot PRO Sealant Injector

I tried the $15 leaksaver can at AutoZone and it lasted 21/2 weeks with no freon left and a frig temp of 50 F with no frost in the condenser in the upper freezer. Then used LeakSaver with a CO2 cartridge and I'm at 3weeks with frig temp 34-35F and frosty condenser. I think it's fair to say it has WORKED! THANK YOU LEAK SAVER!
