3M PPS Type H/O Pressure Cup, 16121, Mini, 4 cups per case

I simply cannot believe the comments that I am reading here. The 3M PPS cups have worked flawlessly in my business, particularly when shooting urethane paints like BM Advance and the SW Emerald version. So much better than the HVLP metal cup with check valve system. It has been flawless. The screen in the lid obviates the need for fine filtering paints before spraying which was time consuming and messy. Honestly, I can't believe these guys are complaining.

I like the concept and design but do have issues with the pressure relief in the bottom of the cup going bad too often and quickly and you can not buy replacements. I also believe it could be made of a better product as they last at maximum 3 months when you use them on a daily basis. They tend to get out of shape and warn which causes you to lose pressure in the cup. All that said it is the best of its kind on the market with less flaws than competitor options.
