I called Spraymaster (Delta Industries makes them) a while back and the supplier that made the original ones (ones from 5+ yrs ago that rocked) is no longer in business. They have gone thru a couple suppliers and believe they have one now that is close to the original design (dark blue trigger). I have still had a couple of these new ones fail on me, but they are definitely better than the ones with the light blue triggers that didn’t seem to last more than a month if you were lucky. The sprayers do have a 5 yr warranty, so you are supposed to be able to exchange them if they die on you. In the past, I have just called them and they have given me an RA# (return authorization#) and I have mailed them about 10-15 dead ones and they would send me new ones. I called them this morning (thanks for the reminder) for another round of this and they said to go back to the store where I bought them now and they should exchange them. So, corporate, any chance we can send these back to you in exchange for new ones?????
