Versatile Backpack Sprayer!
I have to admit that I wasn't familiar with the manufacturer and was wondering how this sprayer would perform. Setup was fairly easy out of the box. Attach the back straps, connect the wand and attach the carrier for the different spraying tips. The battery came showing 3/5 bars charged so I made sure to fully charge it. There is a compartment with a plastic cover over the battery. The spring-loaded door folds down for access. Once inside, the battery stays nice and clean/dry. I give the designer an A+ for that. The sprayer weighs 11.9 lbs. dry. It holds up to 4 gallons of liquid, which will of course add a substantial amount of weight if you are strapping it to your back. I found that the straps were easily adjustable and well padded. Speaking of well padded, the cushion part that is between your back and the unit is super cushy and makes it comfortable to use, unlike some I have used in the past that has very thin padding. Another nice touch. Another great feature is the 5 position variable pressure rotating selector dial on the side of the unit. I haven't used one like that in the past, so it was nice to dial in the best amount of pressure for my particular use. After spraying weed killer for about 2 hours, the battery still showed 2 bars. The manufacturer indicates that it should go about 3 hours. I would imagine that may vary with which pressure you choose, but I could be wrong. In short, I don't think you can go wrong with this sprayer. Give it a shot!

Comfortable and stays pressurized
This is a useful tool if you want to lug chemicals around and spray stuff in your yard. I used this with an herbicide to kill the nutsedge in my lawn. With some nozzle adjustments, it worked really well. It was easy to wear and walk around my yard. The hose and spray gun are long enough to get close to the plants. I look forward to using this more in the growing season. This was easy to assemble. I needed some tools, but it seems sturdy. There is a nice wand holder and 3 different spray tips.

A professional sprayer with useful portability up a ladder and on a roof
This is a lightweight 4 gallon backpack sprayer. I have a 30 gallon one for the tractor to pull for big jobs, a 9 gallon wheeled sprayer for spot applications on the ground, and now this which is something I can put on my back, climb a ladder, get on a roof, and use up on the roof or off the ladder when I want to spray clean something like algae off the shingles or mildew off the siding. This has a twist on knob with additional settings for low, med , or high force spray. There are three spray heads for direct-on spray or degree spray as in 25 degree spray. 4 gallons is about 35 lbs of weight on your back which is all you want when you are climbing a ladder. This is battery powered and the battery lasts a long time. The charger plugs into the battery, and charges it. The battery slips into a back side battery compartment. The leather strapping is very comfortable and durable. The set up is easy; all the parts are in a bag inside the sprayer, under its gray twist off cover. The plastic is hard enough to make me think it is going to be durable. The hose is the right length-too long would tangle your legs. It is very quiet in use; the pump is quiet. I use it to clean siding with a cleaning solution, then I hose the siding off. It has stopped me from pressure-washing the siding so much so it will last longer. I can also use it where I have pests. I can spray insecticide and reach the most difficult places because I have portability. I can get my application where I need it. Yes, I do have to refill it a few times but I would not want to carry more weight up a ladder. For big jobs, this is not your tool. For close up work where you need to maneuver and access spots, this is your tool.

Well designed sprayer for many uses
I have a large yard and lots of flower and vegetable beds. I use several chemicals for control of bugs, weeds, and other stuff that tries to grow where I don’t want it. For the last 15 years I have successfully used a wheeled 3 gallon pump up sprayer. I got this battery operated sprayer to reduce the wear and tear on my shoulders from pumping up the old sprayer. This sprayer was very easy to put together using the well-illustrated instructions. The screws in the upper holster were a little hard to get at, but I prevailed. I like that the extra nozzles have a place to fit in the top holster and that the battery compartment is water resistant. The harness is comfortable and easy to get into if you have the sprayer up on a table or stool. I found the 5-setting pressure control a little difficult to reach but I have shoulder issues. The weight of the full sprayer is around 45 pounds, about the same as a SCUBA tank or fireman’s air pack. Because of the large area that I have to cover I plan to order the heavy-duty trolley for another $40 or so. This sprayer is also good for pressure washing your house.

Great sprayer
I've used this sprayer a few times to spray weed killer and cleaning solution (chlorine / soap / water mixture) on my outdoor furniture. It has fulfilled both of these duties without a hitch! Battery life has been excellent so far as I was able to run about 8 gallons of liquid through it (at the lowest setting) without much battery drain. Thanks to the well padded straps, the sprayer is very comfortable, even at it's heaviest (~30+ lbs when full). All the fittings were watertight as no leaks were observed. As touched upon above, you can adjust the flow rate via a knob on the side. The flow rate at the highest setting is pretty impressive. I used it when spraying cleaning solution, but switched to the lowest flow rate for weed killer application. The pump doesn't make much noise when operating. Three nozzles are included: an adjustable one, 0 degree jet nozzle, and a 25 degree spray nozzle. They attach via a 1/4" quick connect fitting, so you can use any pressure washer nozzles you may have on hand. I found the adjustable one to be the most useful of the bunch due to the spray pattern. The wand holder on the side of the backpack has provisions to store 2 nozzles with the third kept in the wand. Overall I'm very pleased with the sprayer, my only complaint being that the wand has a noticeable wobble to it when it's attached to the spray gun.

Powerful sprayer
My husband has used many different sprayers in the past but they have all been smaller and you had to pump the handle continuously to keep the liquid flowing. Not ideal for a big project. The Silica Slayer 4 Gal.18-Volt Battery-Powered Multi-Purpose Backpack Sprayer changes all that. There are three different quick connect spraying tips and a powerful 18 volt battery with 2.5 hours of running time. The sprayer fits into a holder on the side of the backpack when you are not using it. You can use different chemicals as long as you thoroughly clean out the container after each use. The back pack is very comfortable to wear and the constant flow keeps you going. This is making it so much easier and faster to get work done.

Time saving
This battery powered back pack sprayer saves you time in not having to pump sprayer. When fully charged the 18 volt battery can last up to 21/2 hours on a charge. It has five pressure setting and can deliver up to 25 feet away. The backpack harness is ergonomically made to reduce strain. This sprayer is commercial grade and comes with spray tips plus everything you need. Quick connects make it easy to assemble and disassemble. This sprayer also doubles as a water source for wet cutting tools.

My arm is in HEAVEN!! No more pumping!!
We have a large 1 acre lot and I have to spray for weeds every spring and summer. I have always used the backpack sprayer where I have to pump to get the pressure built up in the tank. This new battery version is my version of heaven!! This brand is built VERY well. The hose is heavy duty and all the connections are metal, not plastic. It comes with three different tips so you can choose a variety of spray patterns. There are also 5 different spray pressures, which you control through a turn knob on the tank. There's a handy storage part on the tank to store your extra tips. I'm not exaggerating when I say this is going to cut my spray time by 2/3 or more. Absolutely worth it if you do any amount of regular spraying. Oh almost forgot to add that they made this thing super comfortable to wear. Lots of padding, and you carry the weight on your hips as well as your shoulders when you strap it on. I'm a 5'7 female and can easily carry it when full. But also equally comfortable for my 6'4 husband.

Powerful portable sprayer
I wanted a portable sprayer that had a consistent flow. The Flowzone 4-Gallon Silica Slayer has been the perfect solution for my needs. It comes with a good operator guide that gives detailed instructions on how to assemble and set-up the device. Only needed a Phillips screwdriver to assemble, most assembly is done by hand. The back-pack mount just clips on the bottom and straps to the top of the tank. With the tank filled I found the back-pack is comfortable and secure. The kit comes with two quick-connect nozzles. There is also a pressure control knob on the bottom of the tank that 5 different pressures. The pump provides a constant flow so coverage is much better than the pump-up sprayer I used in the past. A good tip is to make sure the battery gets fully charged before using the unit. I give this sprayer a two thumbs up!

Sprays Well
This is a very decent sprayer, It comes with three spray tips, an adjustable fan, a 25 degree flat spray and a 0 degree stream, there is also a spray gun, a 53 inch flex hose and a 17" extension wand, all of these have quick connects which is nice. The quick connects are your standard pressure washer fittings. You can run the spray gun with the wand or without. Or you can hook the hose to something like a saw that you would like to supply water to. I would like to see an adjustable that puts out a little less volume. All the assembly that is needed is to attach the quick connect hose, wand and spray gun. Also there are 2 brackets that have 2 screws each that are for holding the spray wand, then the backpack portion is attached via 2 straps at the top and 2 clips at the bottom. There are 5 spray positions on the switch for how fast it will dispense and of course Off. The wand storage is on the side and is not really accessible while you are wearing the back pack, The selector switch is on the lower left side and is difficult to reach when you are wearing the unit. The wand storage clip is very secure but it is too tight and overly hard to put the wand in and take out, the clip should have a little less spring tension. The back pack portion is quite comfortable and has a wide range of adjustments. The sprayer without anything in is weighs about 14 lbs, so with the full 5 gallons of water it weighs about 54 pounds. The spray will reach about 28 feet with the zero degree nozzle. With the sprayer running on the number 5 setting and the 0 degree nozzle it will put out about a gallon of water every 100 seconds. Running constantly on the number 5 (or highest) setting the battery lasted 1 hour and 35 minutes and took about 2 hours to recharge.You can check amount of battery charge by pushing on the battery icon on the battery. The top clip on the wand storage also has places for the tips to store. All in all a very nice sprayer, but I would like to see a different wand storage and relocate the switch. Side note, it seems as if this is the same sprayer they sell with a wheel kit, just without the wheels, even the box says wheeled sprayer, but it does NOT have wheels just the backpack. I wonder if you could buy the wheel kit for it, that would be nice.
