I have 3 different size tank sprayers (1,2,3 gallon) and was tired of carrying them around the farm. We have a 300 ft barn lane and 400 ft drive with a half circle turn around with gravel surface. I use 6 gal of spray to keep weeds/grass out of drives. We have 3 pastures totaling 20 acres surrounded by woods and 26 acres of woods in a woodland management plan. I needed a sprayer that I could use to kill invasive species along the pasture edge and in the woods. This sprayer does the trick. It worked perfectly right out of the box. The wide mouth on the tank with a screen allows you to pour chemical easily into the sprayer and the screen catches anything that might fall into it. I was able to take water, chemical and sprayer in a trailer to the back of the property, mix it the field and spray the pastures edge. I used 11 gallon of chemical first time I used the sprayer and it worked great. No leaks, 5 or 6 pumps pressurizes the tank with excellent spray coverage. With the wand I can reach 10 ft high and the spray is another 3 ft so I can reach places I couldn't reach with the hand held sprayers. Having the sprayer on your back is much easier than carrying around a tank and having to stop to pump 12 or 15 times to keep good pressure. I thought I would use more chemical due to the excellent spray coverage but I was pleasantly surprised that I used less chemical than before. I was able to spray about 1000 ft of pasture edge with the 11 gallons of spray. We have serious problems with Chinese bittersweet, grapevine and privet so I use Crossbow in the sprayer. Clean up was easy, the filter on the wand is easy to get to, the nozzle is easy to remove. The one thing I can't use it for is walking thru brush to get to invasive plants that are well hidden but I knew that before I bought this sprayer. With a tank full of spray on your back it is hard to maneuver in close quarters. If you are looking for a good sprayer, at a fair price that does the job intended then look no further than this sprayer. It is well worth the investment. One caveat is that any piece of equipment is only has good as the maintenance so I would encourage you to clean after every use, use vaseline on the o-rings and take care of the equipment you purchase.
