Weak spray, loses pressure immediately.
P. OLEARY
Updated 2007 - Unlike other cheaper sprayers I have bought, this one is still as good as new after two years of hard use.

Love the fact that I just walk along spraying and it keeps great pressure as it rolls along.

Updated 11/29/12 - I keep thinking I'm going to switch to one of the electric models but then I pull out my old Gilmour and just use it. My brother prefers the backpack sprayers but there too heavy for me. I do have to walk in circles at time to charge up wheel pump sprayer but it's good exercise.

Updated 7/4/2011 - Current one has lost it's fortitude and I get about a second of spraying without walking around. I hate to order a new one but not too many alternatives. I have one that pulls behind the yard tractor but that's too big and doesn't have a wand. I could get one of the back pack pump ones but I'm not keen on carrying three gallons of Round-Up on my back. Amazon sells an electric wheel sprayer with good reviews but it costs $270. Guess I'll buy another repair kit.

Updated 9/21/10 - I revamped one of the old sprayers with the Glimour R12C Telescoping Sprayer Wand and the Replacement Valve R58C ($20 for both). It sprays fine but I was only getting about 4 seconds of spray from a fully charged sprayer. Then I discovered that it pressurized better if I pushed it in front of me (the wheels rolled better). So I had my brothers redo the wheels so that they roll better in general, thus keeping the sprayer pressurized. Still not as good as a brand new pump but it works for me.

Updated 8/10 - After 5 years the only problem I'm having is that the sprayer leaks and doesn't totally quit spraying until the pressure is gone. Because I keep it full of Roundup, this can be a problem but it looks like I can replace all the parts for less than $25. In fact, I think I'll replace the parts on the first one I bought in 2003 and have two working sprayers.

I was so happy to find this sprayer, originally. I have MG (myasthenia gravis), an illness that causes profound weakness with any repetitive motion. So pumping a sprayer to spray my 100+ rose bushes made me too weak to carry the sprayer. I thought this was just the perfect solution, even at $.. that I gladly paid. It worked fairly well at first, although the hose could have been longer and it tended to tip over frequently if you didn't keep one hand on the handle. When it tipped over the spray solution would run out the overfill hole, so I was constantly having to stop spraying to pick it up. At first it pressurized well with 50-60 ft and would spray 5-7 rose bushes before needing another 50 ft walk to repressurize it. It had an easily adjusted and quite fine mist nozzle, an almost wide enough opening for mixing the chemicals, and was very easy to disassemble and thoroughly clean. Since the wheels carried the weight, it was quite effortless to use (except for the tipping problem). Being only about 10-12" wide, it will follow you into almost any place wide enough to walk into, and is easy to give a little extra "sloshing" to keep the mixture well mixed as you go along. It uses all the mixture with very little waste and you can easily open the handle/lid without losing pressure because it uses a small cylinder in the bottom of the tank that contains the pressurized area. All in all, I was quite happy the first 3 or 4 times I used it, and would have rated it 4 stars.
But then I noticed it seemed to take more and more distance to get it fully pressurized and I was having to pressurize it more frequently. In spite of being extra careful to clean it thoroughly after each use, it got worse.

Here in Texas, we have just about every kind of pest or annoying plant immaginable...fire ants, johnson/crab grass, huge grass hoppers, scorpions, nasty spiders, tough-to-kill weeds, etc.
Needless to say, I have to spray a variety of garden products on my yard, both to keep it looking presentable and to keep it safe for bare feet. I've used a common two-gallon pump sprayer and a 4-gallon backpack sprayer for years to apply weed killers and insecticides, but carrying a 16-30lb container around a 10,000sqft. yard gets old pretty quick.
This Gilmour 4-gallon sprayer is awesome! No carrying, no pumping, and no backache. You just push it about 25-30 ft, and it's pressurized. From there, movement around the yard keeps the pressure up. The sprayer also has a nice long hose, so you can reach pretty far back into planted areas, without having to push the sprayer through mulch and soft-earth.
Compared with my old sprayers, this thing has a nice wide mouth, so it's tough to spill chemicals down the side. It's also transparent enough to actually see the fill-points and measurement marks, so overfilling is much less of a problem than with opaque sprayers.
I haven't experienced any problems with leaking or spillage from the filled container, as reported by other reviewers...perhaps the model has been modified since they were written?
This product is also a big time saver, even over similarly-sized backpack sprayers...the push-to-pump (actually, I pull it along behind me) action just leaves you much more nimble, and able to move around smoother. I find that I over-spray much less, use less chemical, and finish about 15 minutes faster (less refilling, less waste, smoother motion and action, etc).
This is definately one of the best garden products I've ever purchased. A truly wonderful and smartly-designed lawn and garden sprayer!
