Roundup 1.25 gal. Ready-to-Use Weed and Grass Killer III Refill

The first one of these I bought would not hold pressure at all. After returning for another one, which I assembled in the store before purchasing, you can hear the pressure escaping, but at least it will spray for a couple of minutes (NOT the 10 minutes claimed). The nozzle is also a piece of crap, with no adjustment for stream or spray. I think I'll need to buy a separate pump sprayer, and buy refill bottles to us it

I have worked too many times to get the pressure. All that comes out is air.

The pump doesn't build up pressure enough to get a normal flow of product. Just a drip at a time. Yes we checked and rechecked on/ off switch wand and the nozzle tip. Can feel the container get pressurized but does not work. So expensive and so disappointed.

I bought one last spring, along with refill fluid concentrate. When I refilled it, the sprayer would no longer hold pressure, so I went back to the store. They looked it over & replaced it. I finally ran out of fluid again, refilled it, and again, no pressure. The store says they replace a lot of them for just this reason, but it’s been too long since I purchased this one - I have to buy a new one. I’m going to try the Ortho brand instead. So, I’m summary: the weed killer works well, just don’t expect the refillable sprayer to actually be refillable! :(
