Sprayers Plus 105Ex Effortless Backpack Sprayer - 20V Lithium Long Battery Life with High Grade Seals & O-Ring, Brass Wand & Nozzle

This is based on assembly and the first use. Out of the box, the pack is easy to assemble. The only issue I had is the diagram for adding the lithium grease is tiny and not very specific as to where they expect you to add the lubricant. Also, there was some water in the pack due to testing so note that you may get some water dripping out of the handle. There is a small orange cap inside the tank at the very bottom of the tank. Make sure you remove this cap and replace it with they syphon screen tube! The instructions leave this step to the very end and I almost did not replace the cap. I think that step should have been near the front.I'm still working on adjusting the straps for the best fit. I'm not a small dude so it's going to take a while to get my custom fit. Even so, the first spray experience was great. No leaks.The battery did not quit and remained strong throughout my entire spray, Nice!I used an entire 4 gallon tank to apply organic compounds to my lawn and garden. Having not to pump the tank to get pressure is a godsend. I used the brass nozzle that came with the pack and I felt the stream adjustments were perfect. No need to swap out for a different spray nozzle head.I think having some of the connections built with metal parts makes this pack appear more durable and professional. Hopefully this will last a long time.I wanted a backpack sprayer that would not quit on me, that had as many metal connections as possible, and that would feel good to use. Based upon the assembly and my first use, I am happy. If it all goes south, I will definitely comment.

I needed to spray weed killer on my one acre paddock and couldn't face using my usual hand pump back pack sprayer. So I bought this one and it did the job very well. But initially it leaked from everywhere. After taking it to pieces and reassembling properly it was much better and now I'm very satisfied with it despite the daft cost of it. I cannot imagine it is sturdy enough to last more than two or three seasons though.

I used the 105Ex for the first time this morning to spray the apple trees in my moms backyard. I found it easy to load and use a lot easier than trying to calculate the mix rate for the chemical! I used the brass adjustable spray head and it allowed me to adjust from a must to a stream but I will look into a different spray head. I mixed up two gallons turned the unit on and put the 105 on my back. It was a comfortable fit and I hardly noticed the weight. It was great that I didn’t have to climb up and down the ladder to pump up the pressure in the tank like I did with the hand pump model! I did notice that I went through the 2 gallons faster than the hand pump but I put that down to the brass spray head. I am very pleased with this unit and I’m looking forward to using it in a week to apply lime Sulphur to the apple tree. I would definitely recommend it to anyone that is looking to make their spray program easier.

I have been in the landscaping industry for over 20 years and I cannot believe I have not gotten a battery backpack sprayer till now. It’s so easy and convenient to not have to pump. Also, the added bonus of consistency in pressure when doing turf applications is worth it’s weight in money right there. The battery lasts all day and charges quickly. Get yourself some tea jet nozzles, because the nozzles that come with it are less to be desired. My only complaint with it is when filling to the 4 gallon mark it’s very easy to spill and overflow as the 4gal mark is right to the edge of the lid. Other than that I’ve had nothing but good usage out of it.
