*by S***S on Reviewed in the United States 🇺🇸 on March 29, 2015*

Have already used this several times since I received the product.  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.

    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.  A waste!
