  • Works great
Size: Inventor 5 Classic 4Gal
I purchased this specifically after it was referred to me by a professional pest control technician. It is high-quality and worth the money. It works very well.

  • Versatile, easy to use battery backpack sprayer
Size: Inventor 7 Ultra Long&Enhance Pump 4Gal
The media could not be loaded. These ALIENTABI backpack comes with an 18V battery, 3 different nozzles, you can change the pressure from 65 psi or 95 psi just with a flip of the switch. Plus it makes even spot spraying the yard for dandelions an easier task. I compared this sprayer to my old 4 gallon backpack sprayer which was a pump type which wore me out way before finishing spraying, the shoulder straps on it are thicker and padded, so you really donโ€™t feel the weight. With this sprayer, itโ€™s ambidextrous. You can use either your right hand or your left hand to spray, as compared to my old one where you always had to pump with the left hand and spray with the right. Very tiring process with my old sprayer. I measured the longest distance that I could get with a full battery and the adjustable sprayer nozzle, you can spray up to 33 feet. Perfect for spraying those poison ivy vines that grow up the sides of our fence. On the video I used it to spray the flowers we have with water, also the flower beds where we are growing vegetables and peppermint, itโ€™s excellent also if you donโ€™t have a faucet near to put a hose, this makes it very easy, you can also use it to clean windows or my husband used it to clean the metal on the garage that heโ€™s going to paint in one color. But I mostly bought it to fumigate my backyard this summer for fleas from the neighborhood straight cats and also for mosquitoes which during summer are bad. Overall this backpack sprayer is the best thing since sliced bread, and it turned my four or five times yearly back breaking chore into a quick, easy task. Versatile many ways to use it. 100% recommended. ... show more

  • only lasted a month!
Size: Inventor 5 Classic 4Gal
I use this for my pest control business, I have had this for a month. I don't use it every day, probably 2-3 times a week. Yesterday I was out working, and it wasn't working right. Only very little product came out, so I changed the battery thinking that was the problem, it wasn't. I also cleaned the inside filter, still not the issue. I have no way of contacting this company, there is no contact information on Amazon. I also can't return it because it has been just over a month since I ordered it. Do yourself a favor and buy Flowzone, which is what I normally do but thought I could save some money going with this sprayer. It doesn't even compare! If the company is ready this review, I would love feedback on why after just a month it stopped working properly. ... show more

  • Good sprayer.
Size: Inventor 5 Classic 4Gal
Bought this sprayer to do pest control treatments. Previously used a Flowzone sprayer but purchased this one since it was cheaper. It's functional and everything. My only dislike is the fan pattern it puts out. When spraying a foundation the pattern is heavy at the top and the bottom, while light in the middle. This causes me to go over the same spot several times to get even coverage. I didn't have that issue using a Flowzone. If the tip could produce a solid even band of liquid I would've gave it 5 stars. ... show more

battery life is great. this saves me time and money when I don't have to fire up the hundred gallon nursery sprayer to solve a plant problem. 40 years experience in the nursery landscape trade

  • Great product half the price
Size: Inventor 5 Classic 4Gal
I bought this looking for a sprayer similar to my Flow Zone, but since Flow Zone wanted to double in price I went looking elsewhere. I found this and it has been great. I use it daily as a pest professional. Uses same battery as a flow zone and same tank set up. Great value for the money. I actually like this the hi/lo switch better than the 5 setting switch on the Flow Zone. If you are in landscaping, pest control or someone that needs a heavy duty tank sprayer differently give this a try ... show more

  • This backpack sprayer is a beast!
Size: Inventor 5 Classic 4Gal
I currently own a few sprayers and I must say, this is by far the best sprayer of them all. When I took it out of the box I immediately noticed how well designed it was. The battery has an indicator of how much charge it holds which is super useful. The compartment where the battery is placed is water proofed with a rubber seal around the door which I think the little door will take force to break loose so opening and closing it numerous times won't affect it anytime soon. The battery life seems to be really good. I haven't had the sprayer for a long time, but I used it 3 times so far to spray 3,000 square feet of lawn and it still has plenty of charge so thats a win for me. I wanted a lithium ion but form factors are all unique to vendor. I use SAMSUNG and got to thinking that a charger/battery system is to expensive and the industry standard sealed lead acid battery can be purchased anywhere for cheap. The heaviest portion of the sprayer is the product and the slight extra weight of the battery is insignificant compared to the product. Long term cost wins and these batteries are proven performers. So, this is a really nice sprayer, but what about it's capability of spraying liquids? As I mentioned before, I own a few sprayers and this blows them out of the water! The stream can easily reach the top of my two story house from ground level. It is capable of putting down liquid lawn fertilizer with ease and faster. I like how far the wand extends which also comes in handy if you're spraying chemicals, keeping the mist spray as far away from you. Overall, I love this backpack sprayer. I don't think there's anything negative about it. It's well built and looks like they put lots of effort in the design. I definitely recommend it! ... show more

  • Used it, liked it
Size: Inventor 5 Classic 4Gal
Just got my hands on Alientabi's spray for the first time, and I'm impressed by how user-friendly it is. The metal nozzle lets me dial in just the right water flow for whatever task I'm tackling, whether it's washing my car or giving my flowers a drink. Speaking of which, the green nozzle is perfect for delicate flower care, delivering a fine mist that's gentle and even.And with a solid one-year warranty to back it up, I'm feeling pretty good about this purchase. Overall, great product and top-notch service from start to finish. Would definitely recommend! ... show more
