My Petra HD4000 sprayer was very simple to set up by twisting a few pieces together. The spray time provided by the battery far exceeds my needs for around my property. It is comfortable for me to wear using the backpack straps. I like the very wide opening, which makes it easy to pour in solutions. The unit itself is not heavy. I don't usually fill it up if I don't want to lug around the weight. I am very happy with my purchase and feel that it is the best available. When setting it up, I did need to ask a question, so I can report that it was very easy to get customer support by phone. Further, it was obvious that they know what they're talking about, and that they care about their customers.Updated March 02, 2023: I ended up leaving some kind of solution in my tank over winter. I use it mostly for weed killer, but it could have been just soap water. Or, I don't know what I may have had in there. When I went to use it today, it would spray out for only like three seconds and then slowed to a very lite weak dripping stream and then would stop altogether. The motor seemed strong. The battery was good, as it had been on the charger for a couple of days. I wondered if something may be clogging it up, like debris or maybe some sort of mineral crystallization which may have formed over the winter. I know you're supposed to clean it out after each use and clean it up before storing it, but it got pushed to the side and forgotten while tending to other matters I suppose. I'm not a perfect human.Anyway, it was very simple and amazingly quick to reach a rep at the company. I used their website chat feature, which is my favorite form of customer support. They do it really well. The rep suggested doing a priming with some warm soapy water, so I emptied the winter contents out of the tank and was surprised to see something covering the hole at the bottom of the tank (see picture). There was some kind of whiteish, fleshy, fimly goop congregated around the hole at the center, bottom of the tank which runs out to the sprayer head. I put on a glove and reached in to clear it. I pulled out a snotty bunch of goo. It had filled in the small round perforated cover/filter over the hole, which just snaps off like a plastic lid. There was additional goop beyond the filter pooled up inside that hole. I used a screwdriver and cleared it all out that I could tell. I then rinsed the filter/cap and ran a batch of warm soapy water through the unit. It immediately started running properly again, as if nothing had ever happened.So, luckily that was simple and a testament to a good product. I'm really happy with the sprayer and think with proper and regular cleaning this time, it will last a good long time.

I have only used the sprayer a couple of times but I'm quite impressed by how solid it is, it's durable and will hopefully stand up to the rigours or regular use! It is a little uncomfortable though as it's quite square, so when you fill the tank it can dig in to your lower back, I'm not worried about this though as I have some rugged foam padding to stick along the bottom which should sort it!There's a good range of accessories and nozzles so I should have the kit for every different job I encounter.Still early days but I'm really impressed by the price and build, would highly recommend to anyone thinking of purchasing! 😁👍

I finally got around to using the backpack sprayer. The machine charged up well. The dial allows you to select the strength. This is being used to spray dormant oil on apple trees. The nozzle is adjustable. This is way better than the pump sprayers I had been using over the years and the sprayer completely covered the trees. It does use up the liquid but it aerosolizes the solution well. Make sure you wear an N95 mask and stay down wind of this machine. The pack does have some weight to it before you add the spray solution.Over all this is a good back sprayer that can be used for many different uses.

Brilliant to work and practical
