Here at MY4SONS nothing makes us happier than a satisfied customer.
It may sound like a cliche, but for us, it couldn't be more true. We really pride ourselves on having a great relationship with our customers and doing our best to answer any and all questions, concerns, and suggestions, all while providing a great product.
But don't just take our word for it. Hear it from our customers themselves:
I'm part of a small painting company, and I just wanted to take a minute to thank you for your M4 backpack sprayer... Part of painting exteriors is to spray the ENTIRE HOUSE, from the top of the roof to the ground line around the slab. This was a TWO DAY operation with an ECHO pump sprayer. Not only that, but I have an artificial rotator cuff in my left shoulder, AND NO ONE makes a right hand pump. (WTF?!!)
Your sprayer not only works fantastically as advertised, it took a two day job, and cut it down to only 3 hrs!!
It would be WORTH it if I had to buy one for every house I did!! (Let's hope it doesn't come to that though, lol). After my 2nd house now with your equipment and going strong. Me and my bad shoulder THANK YOU!

I appreciated the great service you guys provided. Thanks Lance.

I just cannot get enough of your sprayer and the quality of the product.
Your sprayer has kept my tomato plants healthy and viable using DE powder and I have plants that are almost 9 feet tall. Last night I pulled a 3.2 lb beefsteak tomato off the vine.
Last but not least, and without disclosing too much, you have got to tap into the world of cannabis growers! Your units are perfect for aerating the solutions without having to constantly be pumping. The ability to leave them plugged in 24/7 and not to worry about over charging, potential of fire etc. You are a perfect fit, and I cannot imagine how your business could explode tapping into that rapidly growing industry.

Best backpack sprayer I've owned. Thank you for a great product.

I just finished using the sprayer for the first time and I was very impressed. It provides nice continuous flow. There was a lot of thought that went into the manufacturing and design of your product. The plastic and metal fittings/hoses are a nice option to be used in accordance with the needs of the application.
A four gallon tank is the largest I've seen and I was pleasantly surprised the shoulder straps fit even a large man like myself. Again, all in all, it is a great product I expect to use for some time.
— George B
Thanks for the quick response. It implies the tech support for this product is as good as the reviews suggest. It's rare to find good tech support these days!

>I had an opportunity to try out the 11 foot extension sprayer today, as the weather in upstate New York finally warmed up. It works very well and has eliminated completely any need for a ladder to reach the higher spots on my house. I did my entire house (insect perimeter spray) in less than half of the time and effort that it has taken me in the past.
Who designed the extension sprayer? It is an elegant, lightweight, and easily maneuverable design. I like the way that the telescoping section is used simply as a support for the inner tubing. A great cost effective approach to avoiding leaky joints.

We bought what I think is now your M4 Gold sprayer last year. First, it has been great. It has made my job 10 times easier. I have to spray along the perimeter of about 400 feet of fencing several times a year to keep the weeds from encroaching and it’s been perfect...[But] can we purchase a new lid w/gasket or just the gasket? It’s a really odd size gasket and I can’t find one in my area...
— Larry C
I'm so glad to hear you have enjoyed the sprayer, and I'm sorry to hear you are having issues. We can simply send you new gaskets for the lid.
Sincerely, Lance at My4Sons
Hi, I have your sprayer, and love it.I've used it four times, and suddenly, it stopped working. The battery is charged. Voltmeter is working. I've checked the wiring. I've removed the bottom and tapped the motor and moved it around. Still, nothing. Any tips on how to get it going again? Thanks.
— Dave L
I'm sorry to hear you are having problems with your backpack. When it is powered on, first make sure the silver rotary switch is turned up, then try pulling the trigger a few times. When the motor reaches pressure it is designed to stop until you pull the trigger on the valve and release the pressure. If that doesn't work, make sure the fine filter inside the tank (the small white capsule) isn't clogged. In the majority of cases that should sort it out. If not, go ahead and give us a call at 707-331-2848 and we will do our best to get to the bottom of this.
Sincerely, Lance at My4Sons
Hi Lance. Problem solved. I hit the trigger a few times and it started up. Great service. Thanks.

To the My4Sons Family,
I want to express my gratitude for your wonderful approach to your customers and your willingness and dedication to insuring we as a group are 100% satisfied with your product.... And of course, that's not difficult because your Basic M4 Bundle seems to be an amazing product now that I have used it about 4 times.
We got off to a rocky start at first because of a missing part upon delivery, but due to my own mistakes in identifying what was missing, I made the situation worse and yet you made me whole despite my mistakes at added expense to you and I really appreciate that. Not many companies would be willing to do what you did and that's what makes you special in my book.
Now about the M4. As you know, I bought the Basic M4 Bundle along with the 11' telescoping wand.... We have a 2 story French country château type house with a very steeply slanted slate roof impossible to walk on. With this year having been so rainy our north facing areas had developed serious streaks of black moldy discoloration. Because of the height and inability to get on the roof, I thought I would have to hire a pro to take care of the problem because a hand pumped, 4 gallon backpack sprayer got nowhere near being able to reach most of the roof. Then I discovered your M4 and though I loved the idea of a battery run backpack sprayer, I still wasn't sold on giving it a try until I found your 11' telescoping wand option as well... So immediately upon experimenting with your M4 and getting comfortable with the telescoping wand, I had to give it a workout on my roof.
I was amazed! Not only could I reach the entire roof from our second floor balcony with the wand, but the spray action was so thorough that it was obvious that my entire roof would be completely and easily saturated with Spray and Forget as is required (unlike the hit and miss application I'd get from a hand pumped backback).
With my first use of your M4, I figure it's already paid for itself.... After completing this job, I began to experiment with the collection of nozzles that come with the package (a nice touch, btw, to have such a collection of specialty nozzles included).... Though I am pretty certain I will be primarily working with the adjustable brass nozzle most of the time, it became obvious while going through the specialized capabilities of the 6 or 7 other nozzles included that I will be able to use this sprayer for tasks I never even thought of attempting with my hand pump backpack sprayer.... I'll use it to mist flowering plants thoroughly with nutrients and disease control products, to spray trees all the way to the top, and to easily saturate our entire network of pea gravel walkways with weed control instead of constantly just spot spraying weeds as they come up.
I'm also considering using it to spray on LastiSeal on our flagstone and mortar shower. In fact, when I need to do it again, I'll use the M4 to apply LastiSeal or an equivalent product on the stone exterior of our home. We know without treatment, water can seep through the stone and actually drip inside the house and in the past, using a brush to apply water sealer from ladders on second story balconies to areas very difficult to near impossible to reach was a very dangerous and inefficient task... Now we'll be able to do that with ease with your M4 + telescoping wand without the dangerous reaching while dangling from a ladder....
So thank you once again for your great product and even moreso for your unique dedication to customer service. And incidentally, your YouTube videos have also been very helpful tools for better understanding on how to use the M4 to its utmost capabilities.
