    • Excellent Product & Lightning-Fast Delivery!
Size: 20-Gallon
I ordered the Spectracide Weed Stop for Lawns Plus Crabgrass Killer Concentrate along with the Chapin G390 Hose-End Sprayer, and I was amazed—they arrived within an hour! I paid the $4.99 expedited delivery fee, and it was absolutely worth it because I wanted to treat my lawn the same day. The Chapin sprayer was easy to fill and use with the concentrate, and everything worked exactly as expected. Being able to order both items and start spraying my lawn immediately was a huge convenience. If you're looking for a good weed control solution and don't want to wait days for delivery, I highly recommend both the products and the fast delivery option. It saved me a trip to the store and let me get the job done right away. ... show more

    • What should you expect of this product? Read on to find out....
Size: 20-Gallon
Okay, there's this thing I do where, before ordering a product on Amazon, I first read the reviews for it. Especially the one star reviews. And, I gotta admit, there are some really, really ummm.....special....people out there writing reviews. And if their grammar is any indication of there manual dexterity then I wonder how they manage to do things like start a car, put on socks, etc. Read carefully and you'll see that one reviewer complained that they could barely reach a first floor window using this sprayer. (Its a lawn sprayer. If you think that for $9.99 you're getting a power washer capable of blasting gunk off of your windows then you should probably manage your expectations.) One reviewer complained that the "jug" kept falling off. (Frankly, I think they're hitting the "jug" a little hard, but that's just me.) Okay, so my opinion...in case you were curious...is that this is a fine product that did exactly what I expected it to do. It attached firmly to the hose with no leakage. The jug...er...bottle screws on tightly and very, very securely. Not once did it fall off or waste my liquid fertilizer. The sprayer also had no problems suctioning the fertilizer out of the jug...er...bottle. In short, it's a fine, sturdy product and it did everything I expected a $9.99 sprayer to do. Tomorrow I'm taking it to the zoo to hose down the giraffes. (I expect to be disappointed, but that's on me.) Oh, and one more thing, the next time you're out driving around, please slow down: the world will still be stupid when you get there. Promise. ... show more

    • Disappointing Performance & Design Flaws
Size: 20-Gallon
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 & Unreliable The 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. ... show more

    • Saved me $600
Size: 20-Gallon
We have a guy who comes out to check on our HVAC twice a year - May for AC, September for furnace. For the last two years he has told me I needed to clean my evaporator coil fins. I knew enough not to use a pressure washer but was still doing it wrong. This year he said it was bad enough I needed coil cleaner. He said I could buy foam in a can but added "Ours comes in a gallon jug that we put into a sprayer." He was trying to point me to the right stuff while not endangering his job. His company would have charged me $600 to clean my unit. I searched for the can foam and this came up too along with the Simple Green Foaming Coil Cleaner. Bingo! Application is super easy. Put the cleaner in the sprayer bottle, attach to your hose. The first pass was both amazing and disgusting. Globs of dirt coming off my coil fins. I was shocked at how much better this was than my previous attempts with just "thumb on the hose". I ended up doing the worst side 3 times and the second worst twice. I used 1/4 of the gallon to do that. You will notice a change in how much foam is produced that indicates when you have run out of cleaner and are just spraying water. Attach the sprayer to the hose first then unscrew the bottle to fill it. The hose connector does not rotate so you want to attach it empty because you are going to be rotating the entire unit. The coil cleaner is very slippery so be careful about spilling on the sides. The sprayer tip is designed to let you get between the slats. Part of what made my previous attempts fail was that the protective slats for the unit protected too well. This solves that. You get under the slats and just blast crud off your coil fins. If there was a smell, I dont remember it so it must not have been strong. The value is through the roof. $30 for the foam and $7 for the sprayer. I should get 4 cleanings out of that. Call it $6 a cleaning vs $600. ... show more
