Update. Product not as described! Got with customer service they took care of the missing parts quickly!!!!

I use this as a hobby houseplant grower, and I go through about 15 gallons a week watering my plants. Previously, I was using a manual pump 4 gallon backpack sprayer. It worked well, but it was bulky (the pump handle would catch things as I was walking by) and it was difficult to simultaneously pump, spray, and try to hold leaves out of the way to see my reservoir levels. So I was super stoked to switch to this sprayer, and have mostly been happy with it. My main complaint is that it is pretty uncomfortable to wear when it's halfway or more full. When full, it's about 48lbs, and only has a chest strap to hold it against your body. The straps are kinda garbage and don't hold well, so it doesn't really sit against your body well and does a subpar job of weight distribution. For this reason, it feels a little unstable when I'm climbing ladders with it full to get plants that are high up. Since I go through so many gallons a week, my back is wrecked by the time I'm done watering, a problem I didn't have with my old manual sprayer because it had a cushy waist belt to distribute the majority of the weight to the hips. It has been awesome to not have to manually pump anymore and the dial for controlling pressure is easy to reach while wearing the sprayer, but the discomfort of wearing it for a few hours is real. PLEASE MAKE THIS WITH A WAIST BELT! It would be worth the extra cost!

When I purchased unit last year it functioned well and helped me replace the smaller manual pump one I had been using. No complaints. Read the manual for the system regarding storing the system for the winter, did everything that was asked and made sure the battery was removed etc. Battery was stored correctly and on my smart charger system (deltran 10 bank smart 12v/6v battery tender). First use of the season, disconnect the battery and go to use it in the sprayer and nothing. Battery voltage dropped off to less than 2v. Confirmed the rest of the batteries on the charger system worked as intended for their respective devices (lawnmowers, tractor). Seems like the battery internals may have some issues with internal connections. Regardless the battery has to be replaced. Planning to reach out to Petra but in the meantime looks like I'm back to the manual system...
