Great product, great customer service!

Having the right tool for a not so fun job makes life so much easier and this is the right tool!! This is a very good product and when I had a problem with a small leak, customer service was right there to help. They replaced the whole sprayer at no cost to me, no hoops to jump through like you get from some other companies. Very prompt, helpful, friendly customer service. If you're on the fence, buy it, you won't be sorry.

Yes But......

This battery powered sprayer was easy to assemble and allows the user to cover a lot more area than the typical hand pump sprayer of the same size. I really like that feature. The sprayer looks to be well made, and I think it will be durable if properly cared for. The sprayer is easy to clean after using and can be used for several different types of chemicals. There are several different types of nozzles included so it is versatile. Now the cons; The straps don't secure very well so you have to feel for the place to attach it once you get the sprayer on your shoulder with one of the straps, you can't see the attachment point so you have to find it with your fingers to secure it to the bottom of the sprayer. The nozzles and wands are finicky, if not adjusted just right are prone to leak. There are no definitive liquid measurement indicators on the tank only indentions at intervales which I assumed the top indention was 4.2 gallons.Today, 9-14-26 I received an email from NP Global customer service. They are sincerely interested in doing whatever it takes to make sure I am happy doing business with them. I am impressed they are interested in making it right.Though I wasn't overly impressed with this sprayer I can honestly say I wouldn't hesitate to do business with GP Global. They truly put their customers first.

Works great

Thing works awesome!!! Beats using a hand pump. You go through your spray material faster than you'd think. So walk around fast & you don't have to hold the trigger down to cover everything. Put the wand exactly where you need it & give it a quick touch of the trigger. It spreads it so evenly you don't need to hold the trigger down for long. Battery last a long time 2 sprays for me. Maybe 3.

Quality sprayer and excellent customer support

PS Global has the best customer service you can find. I lost a small part in the lid and needed a replacement. Ivy, a Customer Ambassador at PSGlobal Customer Service worked with me to identify the part and sent me a new lid replacement. I highly recommend this sprayer, I love the battery power, the high quality wand and the high pressure of the sprayer. Also, if you ever need assistance you can count on excellent customer service.Thank You PS Global Customer Service

Great customer service

I purchased this sprayer in 2022. Of course this year 2026 I couldn’t find my charger. I contacted the seller who was extremely helpful and courteous and replaced my charger free of charge. Best customer service ever.

Great product support

Sprayer is affordable and works well. Had an issue with mine recently after 2 seasons of usage and Proshop Global support replaced it with zero hassle, which I very much appreciated. Thank you Proshop Global!

Customer service I would give a 5 star , Ivy has helped me since my issue with the sprayer wand forming small holes after using a bleach and water mixture , they sent me a replacement without any hesitation , I have had the sprayer for over a year used it a couple of times prior to the bleach and water mixture, overall it's good sprayer

Great customer service

I love this backpack sprayer! There are several nozzles to adjust the spray and now I am able to spray weeds without stopping to refill every gallon (like I used to have to do). The instructions are sparse, but sufficient. My unit did stop charging for some reason but we contacted customer service and they sent me a new unit right away. This is a great product and a very customer friendly company.

Great product and great company

The distance this sprayer can reach is really impressive. I can reach most of a two-story house with siding cleaner from the ground. It came with a variety of nozzles which makes it very flexible for a number of tasks. I am very pleased with this unit and especially with the Customer Service support. It is truly exemplary.

Great Customer Service

I had the sprayer for about 2 years, a portion of the strayer wand rusted with water leaking from the rust. I contacted the company and was promptly sent a replacement wand without charge.

Great customer service and communication. Had a problem with the wand. I expected to pay for a new one, but they sent one at no charge. I highly recommend this company!

Changed from 2 stars to 5 after great customer service

When it works, it has a decent range. But the Troubleshooting Guide is nearly worthless. When the unit stopped spraying, I took the bottom part off and then removed the battery (both are time-consuming) since the Guide suggested undoing and redoing the 2 battery attachment connections. That must be a left-over fix item from before since you can't do that to soldered and crimped connections. With no mention in the Guide to alert you, I then just happened to stumble on the little screen filter on the bottom of the spray chamber. It was plugged from the suspended solids of the pond spray I was using. So I removed it and cleaned it, and the spray pressure returned. The catch is that you cannot screw the filter back in. Whatever the mating part is inside the hole gets pushed in so no amount of pushing and turning will get the filter back in. Crappy design. So now I will have to run sprayer without the screen filter in place, which will likely ultimately destroy the pump impellers. Then I will have to return it. It does have a lifetime warranty, but you have to pay to ship the defective item back to them.Follow up 6/21/2026 Changed rating from 2 stars to 5 stars since their customer service sent me a replacement sprayer that is working just fine. They even followed up to make sure.

Poor quality and poor customer service

Only used handful of times. Had issue and company went out its way to take care of it. 5 stars for customer service !

Company stands behind their products. Customer service was excellent.

Sprayer itself worked great. I had issues with the metal wand, but customer service was fantastic and send me a replacement right away. Yes, you do get two wands in the box anyway, but since the first one wasn't working I wanted to make sure there would be no issues in the future. Worked perfectly. Ivy at customer service went above and beyond to make sure I was taken care of. Yes, you can find similar products on Amazon, but it's the seller that stands behind them that makes the difference. You can confidently trust NPGlobal. No hesitation to recommend.

10 Stars! A company that actually honors their lifetime warranty.

If I could give this seller 10 stars, I would. They did something I haven't seen in years: they truly honored their lifetime warranty.Many big brand-name companies used to be nice to customers and pay attention to product quality, but they stopped doing that. "Warranty" has just become a sales term or an easy bluff. This company actually showed that they believe in and care about their customers.In short, I bought this NP Global backpack sprayer back in 2023. It was working well, but recently, when I brought it out for the season, the lithium battery died. Honestly, I didn't expect much when I reached out to customer service. I only did it because their phone number was right there on the sprayer and was noticeable.NP Global completely surprised me. They stand behind their word. Their customer service team texted me back and kept following up with me until I had a good, working sprayer again.From now on, I am a loyal customer. I don't care if they are the biggest brand name on the market right now or not. I truly believe they will become one of the biggest brands soon with this level of care. Good job. Thank you.

Great product!

Really happy with the product, and with customer service! Bought it at the end of last season, and the weather turned wintery as soon as it arrived, so did t get the chance to even open the box. Come to find out this year. the charger wasn't in the box! I figured I was out of luck, given the months that had passed, but Nope! CS was freat--sent the charger right away. 😀Product works as hoped, and the days of lugging 150' of uncooperative hose to water our beds is OVER!!🎉 Still learning how all the nozzles work, and which is better for our purposes, but I'm looking forward to a much easier season watering our plants. 😀😀😀

Customer service was so supportive.

The back pack sprayer worked like a champ , then for some odd reason it would not pump but the customer service was so impressive, they had another one shipped within a day and received it in 5 days . They were so polite and very helpful. Five stars from me !!

Awesome customer service

I couldn’t be happier with this backpack sprayer—not just because of the product itself, but because of the outstanding customer service behind it.The sprayer worked great right out of the box: solid build, comfortable to wear, and it delivered consistent pressure for even application. It made yard work way easier and more efficient than I expected.I did run into an issue with one of the components agyer about 2 years. I reached out to customer support expecting the usual back-and-forth, but instead, they responded quickly and handled everything professionally. No hassle, no runaround—they shipped out a replacement right away.That kind of service is rare these days, and it honestly made me trust the brand even more. Knowing they stand behind their product gives me confidence that I made the right purchase.If you’re on the fence, don’t be. The sprayer does what it’s supposed to do, and the company has your back if anything goes wrong. Highly recommend.
