I like the heavy duty design, the thick walled container, thick walled screw on top, and metal charging handle. There are only two concerns that I have with this sprayer. First, for my purposes it needed to be bundled with a adjustable fan tip. I have ordered the Chapin Brass Fan Spray Nozzle P/N 3-6001. I hope that it does the job. The other concern is that whatever drops on to the top while working, especially liquids, get injected via the pump into the mixture inside the container when the user pumps the pump. In other words, when I'm working under my house my gloved hands get very dirty. When I reach to pump the sprayer, the dirt on my hand mixed with the sweat and spray falls onto the top of the sprayer. The problem this caused is that the dirt around the O ring in the pump allowed the pressurization to escape through the pump. I.E. the sprayer wouldn't hold a pressurization charge. I had to completely clean the sprayer, re-grease the pump, refill the sprayer, and then it would hold a charge. So, just be very careful when using this sprayer in a dirty environment and try to keep the top as clean as possible. If it does get dirty, you can rinse off the top prior to pumping and that should keep the dirt out. However, if the dirt gets into the pump, you'll have to clean the top and the pump in order to get the pressurization to work again. Overall, this sprayer is very nice and I would recommend it to all.

This Chapin Premier 2 Gallon Sprayer is a great sprayer, works, very well. The pump is easy to use and stores enough pressure to do work without always stopping. The plastic is solid and sturdy, and the handle is easy to use. I had to fill it 1.5 times to be able to apply liquid pesticide around my house. I'm glad that I got the 2-gallon version, so I don't have to stop and refill as much. I highly recommend it.

This is by far one of the best sprayers on the market. I own two of them, one for weed killing, one for pesticides, etc. When compared to the ones you can purchase at building supply stores it is far superior.
