12 Purchased doses have failed 3 their service. Not old, loud MHD few months. Different guns tried (also purchased from Pritex) ... nothing. Pushed to the nipple of the can, there came sideways pressure and foam out, but not in the middle where it should. Mail contact with Pritex sales receipt and statement and ask if possible production errors: get the answer that it must be an isolated case and I calmed down could buy the product. Do not prompt the cans to send the check or for replacement. Otherwise I think the foam class, sticks well, expresses little. But 25% failure ????
