Review on 3M 26580 Accuspray Spray System by Auden Paz

3M's AccuSpray system is a brilliant concept. I love it ! The problem is that the replacement nibs don't fit the pen well. I can get one side to "click" with a bit of fiddling, the other side refuses to click properly no matter what I do. This goes for all the plastic tips included in the kit, as well as the box of extra 1.3mm tips I ordered. This is completely unacceptable - and truly disappointing. ready to paint. So that's for the 30 day return period (my mistake). So I found that if I use a large elastic as shown in the photo the ends stay in place well. I called 3M and got a quick call and phone number from a local 3M representative who was supposed to help me. He doesn't answer my calls. sigh. I recommend 3M to create a design tolerance stack and release a new version of PPS 3.0 that says "New! Improved! Now with posi-lock attachments that really CLICK!” It's just that the dog was really disappointed with the one-size-fits-all nozzle. Otherwise great concept. I recommend you buy it, BUT once you receive it, MAKE SURE the attachments "snap" as advertised. If not, send the gun back! If 3M brings back enough of those pathetic pistols, they might even change the design to fix this problem!
