My use is for personal homeowner turf care. I became interested in a battery backpack sprayer this year after a lifetime of using a pump. Was primarily interested in getting a more consistent pressure to deliver the product. I read many reviews on options and decided to buy the FlowZone cyclone. I have been very pleased with this sprayer! Well made and simple to operate. Set up was easy and the nozzle quick connect is great. I use teejet nozzles and they work great. Spray gun delivery is fantastic. Variable speed pressure helps gives flexibility in calibrating. The strap system to wear the sprayer is comfortable. The top strap connect does not work well for me as it rides up too close to my neck would be my only negative. The spray tank markings are easy to see. I have no doubt I am going to really enjoy using this FlowZone sprayer and highly recommend this product. And of course DoMyOwn never lets me done with quick delivery of all my orders.
