From the published reviews

Customer feedback at a glance

Editorial summary of 33 customer reviews, reviewed September 30, 2026. These are individual experiences, not independent product tests.

Customers often describe convenient can changes, straightforward use and good value. Experiences with sealing vary: several report leaks, including one five-star review describing leakage from the first use.

Questions about the feedback

Do customers report a reliable seal?

Feedback is mixed. Some describe a leak-free seal, while others report leaks around the can contact or puncture point. One reviewer mentions difficulty sealing thin cans that dent easily. A high star rating does not always mean the written feedback is positive.

I purchased this because the one I had (was a great mechanics grade, which are hard to find these days) broke after 15 to 20 years of use. I found this one online the reviews were okay and honestly, I couldn't find any others that were any better. After spending hours of research (I'm OCD like that) I figured I would give it a go. The product has leaked at the puncture point from day one. It has only gotten worse after multiple uses. Replacing the rubber seal doesn't help. The curvature of the product is not the same curvature of R134 cans. I lose more freon then what goes into the vehicle while charging the vehicle's HVAC system, and you can sure hang up saving any freon that may be leftover.

AC Can tap

Thought I would try this had an old R12 one, needed 134 type. This looked ok shipped quick. But First time I tried to use it, it leaked badly where rubber grommet contacts can. Tried a second can of freon too, same result, leaks badly. I am disappointed & returning. They have agreed to refund me.
