### ⭐⭐⭐ Did not work for me.
*by A***E on September 16, 2023*

This product did not work for me. Product came in a good package. Easy to use, but when I actually fixed the leak there was no product in the line or around the leak... did I use it wrong? Or was there not enough for my 4lb mini split unit?
