Ukoke U04GS Cordless Electric Power Garden Sprayer, 1 Gallon Tank Portable Handhel, 45 psi & 0.132 GPM (500ml per min)

3/31/19 Update: I received a new sprayer as promised. As with the original sprayer, the clear plastic tubing that goes into the tank is bent, so it does not reach the bottom of the tank and would not spray with the tank less than half full. I poured boiling water over the tube to straighten it out. Now, it is only slightly bent and the inlet lays on the bottom of the tank, so it continues to spray until the tank is almost empty. I checked tightness of all of the fittings before use and didn't notice any leaking. Despite these minor issues, the adjustable spray wand works great. It can be easily adjusted for a fine spray or stream, which shoots out about 12-15 feet, maybe more. I was very impressed with the quality of the spray. I like that the sprayer is battery operated with no need for constant pumping. It is lightweight and very convenient to use. I will change my rating to a 4.3/20/19 Update: I updated the rating from 1 to 2 because Customer Service at Ukoke was very responsive to this issue. But, they are sending a whole new sprayer instead of just the defective part, so that required me to pack up the whole sprayer to send it back. Unfortunately, I had thrown away the outer shipping box and did not have one that large available, so I had to make one out of some old boxes. What a hassle. They did send a prepaid shipping label. I'm hoping that I don't have the same issue with the new one. If all works out ok, I will give them a 3. I still really like the sprayer, when it works.I would like to give this a better review, but there are too many problems to give it a good rating. First, I had trouble getting it to prime. It would not spray at all. The problem is that the clear hose that goes into the tank is bent and does not reach the bottom of the tank, so it will only spray when over 50% full. I heated the tubing with hot water to reshape it. It works better now. Secondly, there were several leaks in the spray wand (metal part) and at the ends of the plastic tubing. I had to retighten all of the fittings on the metal wand to stop the leaks. There is no information in the manual about tightening the fittings. Seems to have stopped the leaks in the metal wand, for now. The fitting where the black plastic tube (part of the wand) enters the tank also leaks. I tightened it by hand as much as possible, but it still leaks. The ferrule at the end of the tubing is crooked and the nut makes contact with the body of the fitting before it is completely tight. Seems like a design issue or defective part. I wrapped a lot of Teflon tape around the ferrule and that has stopped the leaking, for now. There is no parts list for the sprayer, so good luck getting parts for it. I contacted customer service about the issue. They did not seem to understand the problem and asked me to send a picture of the issue. So now, I have to remove the Teflon tape and make it leak again to show them the issue. They said they did not have spare parts, so I'm not sure how they will resolve the issue. Maybe send me a whole now sprayer. Hope I don't have to ship the old one back. I will update this posting if they are able to resolve the issue. Too many problems for a new sprayer. It does work great, when it works. i wouldn't use it to spray anything that you do not want to contact your skin.

Doesn't hold constant pressure. Either design flaw or defective pressure pump. Frustrating to use. (Later) I didn't get around to opening the box and using it for about two weeks after it came and now I find I can't return it because the return window closed a week ago. What a crummy product.Later still. Apparently, as in so many complaints, it was the nut behind the wheel. I wrote UKOKE and explained the apparent problem and they wrote back promptly with a couple of suggestions. When I tried them, the sprayer worked perfectly. Well, maybe not perfectly, but as well as, maybe even better than, one might expect for the price. My apologies to UKOKE. Four of five stars for the product and the fifth for their service department.Later and last: I tried to use the sprayer this spring and it worked for about 10 seconds and then lost power. Nothing I could do would coax it to work. I have written the UKOKE company three times in 5 weeks, telling them of the problem, verifying the purchase through Amazon and sending them the warrantee--a three-year warranty according to their manual--information and have yet to hear from them. I hereby rescind any recommendation I may have made for this company. Apparently there is no way to give them zero stars.

I really hoped this thing would be it! I wanted a dedicated sprayer to squirt pesticide up into the eaves of a 1 to 1-1/2 story house/ shop and out buildings. The pump up standard type of sprayer works but the spream fails as the pressure in the tank drops. Wanted to get a battery powered sprayer for a consistant powerful stream. Saw the big backpack power units but they were pretty spendy and were rather big and bulky. I wanted a small one where I could whip up a small batch of bug juice in 1 gallon units, and use it all up in one spraying session.Got it and assembled it, plugged in the battery into the charger (only took about 20 min for the red charge lite to turn to green) Filled it with water and flipped the switch... and ... nothing! Motor kicked on but no spray. Motor sounds just like an aquarium air pump just humming away! Finally, the tone of the motor changed and it started to work.... sort of.I'd get a powerful squirt for just a split second and the stream would immediately fail and go to a mere dribble out of the tip in a mere second! Over and over. Turn it off and back on and same thing. A humming that would not squirt changing to a coarser hum and a split second stream that immediately peters out to a dribble. I sent it back and had Amazon ship me a replacement. Guess I got a lemon! It happens!Got the new teplacement one yesterday and THIS on doesnt even work at all! Motor again sounds like a fish tank air pump and it doesnt change pitch at all. Nothing comes out of the nozzle at all... not even a dribble! I made sure there were no leaks, that the pick up tube was in the water, all connections tight, battery fully charged. NOTHING! Very, very disappointed! I really wanted this thing to work as advertised! A 45psi spray? Not even close!Contacted Amazon today and they made it right and refunded me. So much for great ideas! Think I might try to build my own since there really isnt anything else out there...

This sprayer was expensive, so I expected some degree of quality.Im very disappointed to find that it leaks where the spray hose contacts the tank.The unit also leaks where the base (liquid container) contacts the power unit (top)These leaks can not be repaired because of the design.. "O" ring seals would have solved this issue at a very low cost.

I've use the sprayer less than 10 times and the it stop working. I looked in the pump and there was nothing blocking it from working it just stop pumping. It starts out working well, but shortly afterwards nothing come out. And guess what it stops working 3 days after the return period. In my opinion not worth the money

I filled the sprayer with chemical, expecting it to work. It didnt, it was just sucking air. Luckily my partner took it apart and put bits back in the places they should have been in the first place. Now it works. Not manufactured very well, but worth the effort eventually.

Good quality product, works great, nice and light to handle with the metal wand and spray head gives a good spray pattern. I recommend this product. Larry R

Great machine! The best part is the customer service, amazing! Great communication and went above and beyond my expectations. I will definitely buy from them again! Thanks!

Me gusto.Hace muy buena aspersión.
