MY4SONS M4 Cordless Battery Powered Backpack Sprayer - Includes Battery & Cha...

First of all, this is the only backpack sprayer I have ever used, so I can't compare it to others, quality-wise. And frankly, I didn't ship around, so there may be others just as good at a lower price; I don't know. Having said that, I love this sprayer. So far, I've used it to spray Talstar insecticide around the perimeter of my home, Neem oil on my Sago palms, and Roundup on weeds. It works great. I like the fact that it has a switch for full power, and a rotary knob so you can choose a lower power. Recharging the battery is easy. The sprayer came with several spray nozzles, but I've only used the flexible one and it is very good. Yes, the sprayer is a bit heavy if you fill it with four gallons, but even my petite wife can use it with two gallons in it and she says it makes spraying the Sagos much easier for her. So to sum up: I love using a backpack sprayer in general as opposed to a sprayer jug that you have to carry around. And specifically, this one fill the bill for me in terms of quality and utility. By all means, shop around, but I think the average homeowner will be happy with this particular sprayer.

***Notice my update to this review below***** Received this sprayer yesterday. Have never purchased anything like this before using the cheap ones you pump and carry around. I have two properties that require spraying of something constantly during warmer months. All the reviews got me excited but I have to admit I am a little disappointed. Mostly quality issues. First, the Velcro battery strap was ripped at the left side negating the job the strap has to hold the battery in place. How does something like this ship? Next, upon water testing (everyone should put water in first and test all the nozzles etc.) the unit leaked at the base of the tank where the hose fits in for the nozzle. Investigated and discovered that there was no washer. No Wonder! Perhaps they have their kids putting these things together for shipment. I tried the various spray nozzles and noticed that the ones with more back pressure caused the black plastic wand to leak at the base where it is mounted to the trigger. I tightened this up with my hands and sprayed again and noticed that water was spraying out of the shaft of the black wand. It was streaming out but I could not make out any holes etc. Must be micro splits vertically at the end of the shaft. I switched to the metal wand and this did not happen. Not sure why I got a plastic and metal wand but at a minimum I'm glad for the metal wand. There was also a flexible white hose similar to ones used on a washing machine however I have yet to discover a use for it. Documentation is horrible. It shows components that did not come with my unit and nothing explaining their purpose. I discovered their use by hooking each one up noticing that some created a spray, others a larger spray and then some created a stream. Some spray with two nozzles etc. Lots of choices which is good but better documentation or perhaps a Youtube tutorial is in order. For as many as they have sold, they could have put a Youtube tutorial unboxing, putting together and explaining how all the nozzles work and what jobs they are made for. Would have been nice to see a video showing them dealing with the quality issues on mine.....however I bet they would not publish that. So, I tried to call their support line and got voice mail. I don't leave voice mails because if companies call back, it is always at the worst time. So, I'll try again later to see if I can get a new wand and a new velcro strap to hold the battery in place. All in all I think it is a good tank and pump system however they should offer a Li battery option as it would make it lighter. I'll update after talking to the manufacturer and getting the replacement hardware. ***Update*** After posting this review but before it went public I got a call from the owner who had seen that they missed a call. I went over my issues and we discussed all three of them. He admitted that he had problems with shipments where the battery moved around around if the box was tossed about during freight. He went on to explain that the strap over the battery was really not even needed now since he modified the door housing to make it stronger etc. I agreed with him on that. He agreed to send me a new black wand which we received yesterday. We also discussed more documentation of a video on how to open and put together and use the various nozzles. He was a really nice guy and I could tell he cared and wanted me to be happy. Never once did he mention not putting a negative review which I always appreciate. His main concern was making sure I was happy. We talked for 30 plus minutes about how this product had evolved based on feedback etc. We also talked about battery options and he explained that Li batteries would greatly increase the cost and the weight savings would only be about 2.5 lbs. The main weight in in the products you stick in the tank.

I Ordered my MY4SONS M4 4-Gallon Sprayer Sunday and received it today (Saturday UPS) coming from California to Ohio. The package was packed very nice and everything was labeled with Great Instructions. The Quality AND ATTENTION TO DETAIL IS AWESOME! The battery was fully charged and ready to use. I will be using the Pistol Sprayer most of the time so I installed it directly to the hose and was using it within 20 minutes. I will be using this unit mostly for spraying lawn chemicals for weeds and fertilizer. The Cart is Great Quality as well. Very light weight strong aluminum with big wheels that will work on any surface. It has very nice yellow elastic straps the connect the unit to the cart quickly. For a Test I sprayed 4 Gallons of water through it to wash the drive off. I decided to wear it on my back to test the weight with 4 gallons and it didn't feel any heavier than my backpack yard blower. I had the pressure turned up about 3/4 way and the spray traveled at least 20 feet with very good velocity. After further inspection I noticed the black shoulder strap adjustment pieces were made of steel instead of plastic which will hold up much better. There are so many accessories to choose from. The Black Storage Bag is very nice quality as well. I'm so impressed with this unit for both Quality and Price. Thank You for Engineering a Great Product!

Thought I'd wait until I used this at least twice before commenting. First........this sprayer works great. Spray is adjustable from a mist to a stream. You can adjust the pressure so you control it when spraying small areas or up close. I can reach all the way up to the eaves on our 2 story home with no problem or spray right at my feet without making a mess. It is heavy when filled but the wide shoulder pads make it quite comfortable. I am 70+ and I can handle it with no problem. The only criticism I have of the sprayer is the clip that holds the wand in place. There is just one clip up near the top and it is flexible and the wand is swinging and bending all over the place. It may be good for storage but when walking with the sprayer to get to where you want to spray it becomes a bit unruly. No big deal, I just unclip it and hold it in my hand. It does not hold the wand vertically like it shows in the picture. It's a great sprayer. I did a large area in half the time it used to take with a pump handle sprayer and got much better coverage plus it is much more versatile with variable spray tips and adjustable pressure. It's the best sprayer I have owned and well worth the price.
