Review on πŸ’¨ Efficient A/C System Flush Kit: MASTERCOOL (91046-A Silver) for Optimal Performance by Sean Maples

Revainrating 3 out of 5

Good price for casual users. Not recommended for frequent users.

Works, but the air valve is annoying. The entire Schrader valve assembly is cheap and difficult to fill with air. I filled it halfway with solvent and had to keep pressurizing the air because the valve kept leaking. I will replace the Schrader valve when I use it again but for the time I need it; it succeeded. One of those things you get what you pay for. This is great for occasional users, but using it more frequently can be frustrating.

Pros
  • Pleasant to use
Cons
  • Good, but not great
