Today I used this sprayer for the first time. I was definitely amazed by ease of use, functionality and absolutely no drip or leakage. I tried to research as to how much to pump it up since no gauge but was unable to get any info. It didn't matter. With tank pressurized or low on pressurization it still shot a remarkable stream on the baseboard/floor. After ordering (with pistol nozzle) I was questioning myself if I should have ordered the sprayer with the wand to get closer. I have to now say I'm glad I didn't. After about 5 seconds, I was spraying like a pro ????. I used a pin stream indoors along baseboards and exterior doors and windows. Then a fan pattern along the exterior of our house. Both patterns were perfect. Not sure on your preference between pistol or wand but if you're thinking about one of these sprayers from B&G, you'll definitely be impressed.
