Master Paint System MPS Disposable Paint Spray Gun Cup Liners and Lid System, 50 Pack Mini Size 6 Ounce (180ml) Kit - 50 Cup Liners, 50 Lids with Strainer, 1 Hard Cup with Retainer Ring and 20 Plugs

Overall they work well. Had a few that didn’t seat correctly on the gun and leaked

Returned

Tried using this junk 3 times 1 time it worked without leaks 2 times leaked dripped everywhere. The cap sealing to permanent cup seems to be an issue as with other users. All three uses resulted in the cap breaking off inside the adapter that you BTW must purchase elsewhere for 25 bucks. Going back to old way this is a waste of time and money.

no leaks from cup system. Harbor Frieght cups system leaked like sieve. Bought brand new cup and leaking was the same. This system kicks butt!

Saves some time in cleanup, but the best feature is that you can see how much paint product you have left at all times.

Great packaging! Easy self explanatory operation. Great product for clean environments.

I used this for painting cars and it worked great

Works as described

Ive have used the 3m pps cups due to budget but these make it affordable for me. I ordered the correct adapter for my devilbiss set and have used these with primer gun so far with no problem.

The lid is a little tougher to get on but for the cost they are great. The lid does seem to go on easier with their cups rather than a 3m cup.
