Chapin G390 Hose End Sprayer For Water Soluble Materials, 20 Gallon, 32 Ounce Tank, Finger Control and Backflow Prevention, For Spraying Lawns, Weeds, Insects, Fertilizers, Translucent White

I gave 5 stars because Amazon made it right. Sprayer came missing the nozzle lid. Not very useful with just the container! But seller replaced the bottle and the new one came intact. Sprayer works wonderfully! Lots of pressure and makes treating the yard super easy.

We had a serious case of moles digging up our rear lawn. I bought a gallon of the castor oil based liquid and this sprayer. It was among the least expensive but had good reviews. I am impressed. It is easy to use & works very well. The anti-mole/vole liquid said to mix with unscented dish soap. The markings on the sprayer let you see exactly how much of each to use.

This sprayer actually works as indicated. Was able to put product in container and utilize it with the hose. Only problem with it is the area where you screw it on the hose does not turn. You have to turn the whole container which is a pain. It should be made with a turnable hose connector. Otherwise it does work ok

I had high hopes for the Chapin G390 Hose End Sprayer, but unfortunately, it fell short in several key areas. While the idea of a simple, efficient sprayer for lawns, fertilizers, and insecticides is great, the actual performance was frustrating and unreliable.Key Issues & Drawbacks❌ Inconsistent Spray & Poor Suction – One of the biggest problems is the sprayer’s inability to maintain a consistent spray pattern. At times, it barely pulls any solution from the tank, leading to uneven application and wasted product.❌ Flimsy Finger Control – The finger control lever feels cheaply made and doesn’t provide smooth operation. It’s either fully open or shut, making it difficult to control the flow properly.❌ Backflow Prevention? Not Really. – The backflow prevention feature is supposed to stop contamination, but I noticed some leaking and dripping, which defeats the purpose.❌ Difficult to Get the Right Mixture – The adjustable settings are not very reliable, and it’s hard to tell if the correct concentration is being applied. The dilution ratio seems off, meaning I either overuse or underuse my solutions.❌ Build Quality Feels Cheap – The plastic tank is thin and doesn’t feel durable. After only a few uses, I noticed minor cracks developing, raising concerns about its longevity.What Works?✔️ The translucent tank is a nice touch, allowing you to see how much solution is left.✔️ When it works, it covers a decent area—but only if you can get the spray to function properly.Final Verdict⭐ 2/5 – Frustrating & UnreliableThe Chapin G390 had potential, but it suffers from too many functional issues to be a worthwhile purchase. Between the inconsistent spray, unreliable suction, and flimsy controls, it’s hard to recommend. If you need a hose-end sprayer for lawn care, you’re better off investing in a more reliable model.Would not purchase again.

Used it to apply flea treatments to my yard. Easy to use and clean afterwards. The spray was good and it’s durable.

Well, it works and comes with clear instructions for use. However, the screw-on cap is a problem. First, the threads on the bottle and cap are molded too shallow so that they don’t engage very well. Second, the screw-on cap and the bottle have less than a full thread, meaning that when you screw on the cap, it barely turns a full revolution. Result: the cap comes off very easily, it fact it will literally pop off the bottle when it’s bumped during use (especially a full one bottle). Causing the bottle to fall off and spill the solution you’re spraying. If you try to tighten the cap, the shallow threads allow the cap to just pop off instead of tightening securely. This situation doesn’t make the sprayer useless, it just requires some care in assembly and handling/use.

Easy to use and doesn't leak! Great price!

I have 8 dogs. And this product makes flea control easy. Just load, hookup the hose & spray.
