Sprayer works well for quality level, basic homeowner periodic use.All Plastic.US made.Cumbersome when full to move around.Very difficult to read fluid gradations on tank, use a magic marker to fix this problem.Is overpriced at $50, better around $35 for value.Shoulder strap is a silly excuse afterthought accessory not worth using; tossed mine as useless.Seals okay so far.Plastic pump shaft leaves one wondering when, not if, it is going to break.Great sprayer. I’ve bought many 12-20 dollar 1-2 gallon sprayers. This 3 gallon is worth the extra money.I liked the sprayer, but the assembly instructions do not specify how to attach single strapHad a problem out of the box and was concerned, but after tinkering around with it found the issue, The gasket on the cap had some gunk in it and wasn't holding air pressure. Took everything apart and greased and now it works good.Seems ok came inoriginal boxExcellent, More Spraying Time, With Big Tank !Wow. Now I see what all the bad reviews are about. The tank arrived finally only took three weeks I unpacked it and opened the plastic bag the extra nozzle tips that were advertised that come with it and they didn't. The carry strap didn't have any thing to connect it to unless I tie a knot at both ends of it it's not going to carry much. The plastic tube inside fell off the red cap just screwing the top on. I took it out and put it back on after I cut about half an inch of it because of a crack in the top of the plastic tube. Because its a new tank and I test with tap water. I filled the tank with room temp (about 70 F) to the 3 gal. mark put the plunger in and secured it to the tank. Out on my back porch to continue my testing and brake in of the tank. After checking to make sure all the connection were tight. I began pumping the pressure in to the tank. after about 5 pumps I noticed the change in the tank pressure. so I locked the handle in place. Than used the bleeder valve on the handle to bleed out the air in the hose and re-tighten it after it started to leak water. unfortunately it didn't stop leaking water after it was tighten. and I had to wrap the threads in Teflon tap to get it to stop. Because the entire assembly is plastic you can't wrench on it with a pair of pliers so hand tight is the best any one can hope for. From where the wand connects to the nozzle I had to use more Teflon taps as well to stop the leaks. After running the first 3 gal. through the tank. I ran another 3 gal. or at least I tried. As I pumped the pressure up in the tank on the 4th pump the over pressure valve popped open and has stayed open it wouldn't close. (with or with out any thing in the tank.)I don't blame Gatzies (the seller) for these problems. They had no way of knowing this is a quality control issue at the factory. Solo is a German company and their track record for German quality control (or the lack of) speaks for it self. while the problems are all factory issues from the beginning of my placing this order. its been one big let down after another. Gatzies for a lack of communications and there attempt to sell something they didn't even have in stock to Solo's for there lack of quality control.I have a 1.5 gal tabor tank I bought from Harbor Freight last spring that works better than the Solo tank and its make with cheaper material and worked better out of the box than the Solo ever will. (I wonder if tabor sells a 3 gal. tank.)....Well they didn't lie, the wand is still not broken, Just the handle to pump the pressure!!! rendering this $50 sprayer useless. I've used it maybe 4x and it's broken.
