Recently bought this sprayer and used it today. It works great, powerful spray, big padded straps. Easy to fill. The wand is SS and the tip is brass, there is also a plastic tip included. It runs off of one 3 AH battery which should last a couple hours. You easily reach the pressure dial when it’s on your back if you want to change the pressure while operating it. The tank is attached via a couple of buckles which means you can easily detach it for filling and cleaning. So much better than my hand pumped Stanley. Cost was $309.
