the pro is, it worked very well, it dries the pvc connections within 30 seconds.
The con is, you have to check the expiration date, this one expired on January 2018, last week, wanted to shorten one of my shrub sprinklers, but what was left in the can, which was almost half, had already started to dry up, as if I had the can for a year. Lesson learned, I have to check the expiration date once I get the item next time.
