    • EXCELLENT PRODUCT
It's from EGO, what more needs to be said. That said, I've been using this unit for nearly 2 years and haven't had a single negative issue. As the unit is used at least monthly, that would I would consider it highly durable. It's easy to use, and maintenance is next to nothing, just rinse clean and dry the nozzles. I use a 5 amp hour battery and it provides more than enough power to spray the 4 gallons of fertilizer. In fact the battery is way less than half discharged. In terms of weight, yes it's a little heavy when it full, but you are lifting 32 pounds of water. Empty the overall weight, with battery, is more than acceptable. If one is concerned about weight you could always go with a smaller battery option. Definitely worth the money and a very good buy, as with all EGO products. ... show more

    • Great EGO Sprayer. Works great and I would buy again.
I own several EGO power yard tools. I got tired of using hand pump sprayers - Constantly pumping, constantly clogged, etc. I looked into powered sprayers and decided to buy this EGO since I already had several batteries, and my EGO products have always performed well. I just used this sprayer for the first time to apply liquid lawn fertilizer. It was easy to add the solution poured from a Lowes bucket (pre mixed fertilizer with water) as the opening is like 6 inch diameter. It starts spraying quickly. The speed dial is easy to use and at hand. The manual switch on handle has a locking mechanism that works great. The tips are easy and quick to adjust to get the spray pattern you want. High quality parts. Was able to spray 3 gallons to cover 2,000 sqft without losing a single bar on my battery. Has a nice filter where you pour in solution and water. You can pull that out to clean it. Cleaning tank is easy. just fill with water, turn speed to 5 and let it crank out the water. That cleaned the lines really well. I still added water to the tank, shook it around, and dumped it out for a good full clean. Well worth the price and glad I bought. Saves me tons of time and ensures proper application levels. ... show more

    • Tip for top not unscrewing
Works great but a crucial tip the manual doesn’t tell you… After you’re done spraying your chemicals, even after you spray warm water into the canister and shake it around and flush the sprayer wand the lid can still be impossible to pry off next time you use it. Here’s troubleshooting steps 1. With battery plugged into sprayer, spray out the wand until no air comes out. (Didn’t work for me, but worth a try). Attempt to loosen cap 2. Remove battery, spray wand to release last puff of air. Attempt to loosen cap (didn’t work) 3. Pour warm water or wrap with warm towel around lid for a few minutes then attempt to loosen (didn’t work). 4. Take a blunt needle (needle for a ball pump, and push down the rubber plug into the basin, to be retrieved later, to completely remove all air). If this doesn’t work then the cap is chemically sealed. 5. Fill large pot with very hot water, invert your sprayer to submerge the entire green lid for 5 min. The expansion worked for me to allow to loosen. *** what manual doesn’t tell you: after every use remove cap and wash and dry the male and female threads of cap and unit. Never let the unit sit with cap refastened between uses!!!**** If you do this you’ll love the unit ... show more

    • Excellent sprayer but watch the weight!
Not for the weak! With a large battery and 4 gallons of liquid, this thing is heavy. I am a 5' 11" 265 lbs. former offensive lineman (yes I am a senior citizen). With that said, this thing is the bomb! The spray rate and controls are excellent. It has a momentary spray lever and a lock for continuous spraying. The different nozzles provide a nice variation in spray patterns. The backpack strap system is very nice. Weight is the only issue and that is a matter of physics. I would recommend using a smaller battery and a gallon or so of liquid on the first try to see how it works for you and adjust from there. ... show more

    • Ego sprayer a little heavy
I knew this sprayer would be a little heavy but figured the quality of the sprayer would make up for it. I like the ego products and this one is no exception it works great.

    • Need bugs dead? BUY ME!
Absolute GAME CHANGER. Is it pricey? YES. Does it lay down a blanket of insect death in no time? YES! This combined with CyKick CS and you’ll literally make up your own song of things dying in your yard. Put down 6 gallons of this stuff in 30 minutes without breaking a sweat and nothing has moved since. DO IT! ... show more

    • Incredible investment!
Absolutely solid build and comfortable. The weight is nicely displaced even with 4 gallons of water. Battery life is incredible and can easily spray over 1 acre on a single charge. Pressure remains consistent and can be changed based on task. It is well worth the price.

    • Typical great quality you expect from Ego.
This is exactly what I was hoping for. Great quality, great power. Very happy with this purchase. A variety of nozzles helps for different applications, great pressure means you can cover more area with less walking. Remember you’re going to be strapping a lot of weight to your back with liquid, battery and pump etc…. It’s a great unit, but you need to be physically capable of carrying the weight, and counterbalancing a heavy pack while on sloped ground. ... show more
