I recently recharged two old R-12 AC systems in two of my old cars with R-152a (Keyboard Duster Spray). This can tap worked great, although I'm sure I did lose a little bit from each can. The R-152a works great as well, both cars have cool air again. The stuff is not only better for the environment than R-134a but is much cheaper at $5 per 10oz can. ### ⭐⭐⭐⭐ works well *by R***H on Reviewed in the United States 🇺🇸 on March 25, 2016* works well cant beat for the price did the job ### ⭐ A waste! *by D***R on Reviewed in the United States 🇺🇸 on May 15, 2017* No matter what size can is used; it leaks badly! I even tried different seals on it. I think I lost 3/4 of every can.
