YUZES Disposable Paint Mixing Cup System 20 Ounce (600ml) Kit - 50Pack Paint Cups with Lids, Hard Cup with Retainer Ring, 10PCS Plugs, 2 Cup Adapter, Paint Stirrer for Automotive Paint Gun

It was always such a pain to clean the reservoir on my gravity feed gun every time I got done spraying. Now I just remove the disposable cup and clean just the adapter and the short fluid path in the gun (connecting the gun to high pressure and spraying brake cleaner into the cup adapter seems to work quite well for me). I tried leaving some thinned oil-based enamel in the cup with a plug for a few days but it congealed anyway, probably would have been ok in the short term and should work well for just changing colors and then going back. It came with male and female adapters and one fit my gun perfectly. The cups and filter lids seem very nicely made. One of the best features of this type of cup is that the cup collapses as you spray and if you hold the gun upside down and hold the trigger it will suck all of the air out of the cup and after that you can spray at absolutely any angle which you can't do with a conventional cup. I love it!

These work great , the lids snap into place to insure the seal . Bought the ones on Temu , they leaked and ruined a panel paint job causing hours of repair work. I used to use Devillbiss cup system, which also work great but are too pricey for me.

Don’t Easter your money. Still have a half a box left. I go through 2 boxes a month. These leak terribly. Poor design. Probably from China.

Son buenos

The lid collar fitting is not that good . one out of every 5 leaks in the middle of the job

I love this kit and it is at a very fair price. The only thing negative about all of these types of kits is that with darker paints you cannot really open the lid to check the level but really it is just a very minor issues overall I LOVE MY mixing cup system and will order more cups in the future. Thanks.

I started working on a large project that would require painting and cleaning the sprayer over and over, so I decided it was a good time to give these a try.This system works quite well and certainly avoids the chore of cleaning the paint cup on the sprayer.The AdapterIf you don't know, these kits include an adapter to let the plastic paint cups attach to the sprayer.The included adapter for connecting the paint cups to the gun seems to have been machined from aluminum then anodized. It looked nice, and the engagement to the paint cups was precise and never leaked.Where the adapter screws onto the sprayer, there is no o-ring. The connection did not leak because the rim of the adapter bottomed out on the flange of the sprayer, but lack of the gasket means the threads got filled with paint, requiring the adapter to be removed and both the external threads of the sprayer and internal threads of the adapter had to be cleaned out. Removal was tricky to accomplish without paint drips to clean up.The Outer CupThe outer cup had clear graduations and was made out of HDPE or Nalgene or a similar stiff, slick plastic that seemed to hold up fine to powerful solvents, and paint did not tend to stick to it. Cleaning it of moist paint was easy. Over time, overspray built up on it and dried. This made the cup kind of dingy over time. I am not sure how bad it'll be by the time I've used all 50 cups. Maybe they could have given me 2 outer cups.The Inner Cups ("Bladders")The inner cups mated to the lids snugly, and did not leak, even towards the end when the sprayer pulled a suction on them and collapsed them down (as should happen). Some of the inner cups were deformed from being compressed in the packaging. (See Below). In a few cases, this deformation caused creasing, destroying the cups. So instead of a "50 pack" I got what amounted to a "45 or so pack".The PackagingEverything was basically tossed into a carboard box and apparently shuffled around until the flaps were able to be closed. This meant that I had to hunt around in the box to find all the parts needed. It wasn't too big of a deal, but the deformation the sketchy packaging caused to the inner cups reduced the product value.OverallI would say that the disposable cup system shortened my cleanup time, but not by much. I still had to clean the sprayer, obviously. But I had to clean up parts of the disposable system which arguably was almost as time consuming as cleaning out the sprayer's regular cup would have been. Add to this the large amounts of plastic that will be in a landfill long after I'm dead and gone.One standout thing is that you can lay the gun down, you can even turn the gun upside down, and paint will not leak out because the disposable systems don't need a vent hole in the paint cup.So in a match up between convenience, practicality, cost, and ethics, I'm not sure. How I feel overall is complicated.

Love them.
