Right- so much easier to deal with than r134a/r12. No comparison. Ive quit entirely messing with r134a/r12. No such thing as illegal- just interpretation of the EPA laws regarding using alternatives in an R12 system- you have to change out the port fittings to r134a, THEN youre OK.
So much baloney out there by mis-informed individuals on the flammability too. Just beware. All refrigerants are flammable- just at different temps. And ES12 has a narrow band of flammability range (about 2-9% concentration where vulnerable to flammability). very difficult to hit that range in every day driving/crash situations.
