  • 4.0 out of 5 stars Works well
Maybe it's just me but it seems like it's IMPOSSIBLE to get all of the water out of this thing. Other than that it's worked great

  • 5.0 out of 5 stars IS THIS WORTH 229? I SAW EVERY YOUTUBER HAS IT…
1 year update: this sprayer is awesome. Spraying pesticides, pre emergent, weed (no round up or non selective.) the sprayer already paid itself off. It’s awesome and fun. If your looking at this you know your stuff and probably deserve this for all the DYI stuff you do! 🤘🏻 Well that definitely depends. If you take care of your own lawn and pesticides then I would say yes. If you plan on spraying only round up or glyphosate on a small area, then no. FYI I would never put either of those in my 105ex ever. Use pumps for that because you don’t wanna cross contamination. I’ve used this once for a pesticide application and it basically paid it self off. I also will be using it for tenacity, fertilizers, and micro nutrients. I hesitated for to long purchasing this because the price. My thinking…well I can just use my 2 gallon dewalt which is a good sprayer and it was like 35$. Well you can’t compare them. It’s like comparing a Volkswagen Bettle to a Lamborghini. They serve very different purposes. The 105ex is going to give a perfectly even PSI application while the pump just can’t do that. Additionally, the 105 is superiorly engineered and a overall better experience. Will it last? That is always a gamble but with tank cleaner and maintenance; I’m convinced it will. If you leave chemicals in it overnight and knock it around well maybe not. I know you saw it on YouTube on every lawn channel and thought well if they use it… and your thinking well I have a pump sprayer and that works. Believe me. Not like this thing…. Buy it if you can afford it. Btw go for the 4 gallon over the 2 gallon. You’ll be sorry you didn’t spend extra money and use the bed of pickup or stair to put it on when full… ... show more

  • 4.0 out of 5 stars Read this if yours is leaking
I found the brand SprayersPlus through the recommendations of lawn care YouTubers. My first, a 2-gallon handheld sprayer, leaked severely out of the box. Convinced that spending up for a backpack model would mean a more premium product, I took a chance on this 105ex, only to have the same issue with leaking during the initial water test. After multiple rounds of troubleshooting with support and completely disassembling units to install new pumps sent by SprayersPlus, I have now fixed BOTH of their sprayers and the solution is pretty simple: You need to tighten the ever-loving f*** out of the hose clamp. Specifically, if you follow the sprayer end’s hose into the disassembled unit, you will find where it attaches to the pump. There’s a silver ring around the hose at the attachment point, with a flathead screw for tightening. Go absolutely nuts on that thing. As tight as it might be, I bet you can get it tighter by hand than it comes from the factory. None of this is complicated—just removing some Phillips-head screws until the pump is visible, then tightening the clamp, then replacing everything—but I’m pretty disappointed that two units in a row, of different models, had the exact same problem. ... show more

  • 5.0 out of 5 stars Powerful & Long Battery LIfe
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. ... show more

  • 3.0 out of 5 stars Good sprayer with a battery holder flaw
This is a good no-nonsense sprayer, but it has one fatal flaw: the battery has a spring clip that should lock into a hole in the sprayer, but I could not get it to easily engage. Many times, I will think the battery is seated properly only to have the sprayer turn off after about walking 20 feet…major pain when you have a full pack. This may have been a fault w/ my particular battery, but I had do do a little "surgery" on the mounting hole with a dremel in order to get the battery to lock in more reliably. ... show more

  • 5.0 out of 5 stars Retired my Solo Sprayers
These sprayers are fantastic. Life on a farm involves regular spraying for weed control. I have really big sprayers and backpacks. Battery life is excellent, the tip control is as good as I have seen in any backpack sprayer and it is brass. I have two, one for roundup, one for selective sprays. Much easier than having to make sure all round up residual is out of the sprayer. I can use as a backpack or sitting in the back of my RTV and spot spraying weeds or along fence lines or combo of both. That's one of the really nice things about it, it can do both on one tank of spray. My solo sprayers have been retired, these are my go to units now. ... show more
