I purchased one of these as it had a handy accessory that reduced overspray from the nozzle.
Sorry link doesn’t work, try the old copy/paste.
It is different from other sprayers I have used in that the area around the filler neck has a molded mini funnel around it. At first fill you think that’s a good idea as any drips of chemical that spill when adding can simply be rinsed away into the bottle when the water is added. Then when you go to refill or rinse the bottle after use you realise that when the plunger is unscewed and “cracked” if there is any residual pressure in the bottle it blasts droplets straight back at your hand or face if you are leaning over it.
