I have been a big user of neem oil for my new potted peppers over the years until I recently purchased a house and had plenty of space to grow a garden. Soon, my little hand sprayer was inadequate for my setup so I went looking on amazon. The adjustable nozzle is what attracted me to this sprayer in the first place, then it looked well built so I went for it.Just used it and I am just blown away by how effortlessly and quickly I can spray underneath my plants (where all the baddies live). Can be a fine mist that coats the leaves perfectly so I dont have to go in and rub the spray to insure proper coverage. Spraying on top is even easier. I did 4, 8ft garden beds and a 25 foot in-ground bed with a total of about 30 plants in a whopping 3 whole minutes! With no cramped hands!I hope people see this review if they're searching for neem oil, underside of leaves, aphids, thrips. I'll have to post again after long term use. I plan on keeping the bottle mixed and off pressure so we'll see if it damages any parts. Ideally I'd pre-mix in a gallon jug and wash out after every use.
