The Results

We’ll start by saying that this backpack sprayer is designated primarily for homeowners with medium or large gardens. The best part about it is its outstanding power, as it is capable of pumping no less than 150 psi of pressure – this ensures an optimal level of efficiency and performance.

As a matter of fact, this is the highest pressure capacity we’ve tested, being 65 percent more than the pressure of other diaphragm pump backpacks. Plus, thanks to the patented pump design, you can rest assured that the powerful spray will get to those hard-to-reach areas, creating precise spray patterns.

Another noteworthy characteristic is the durability of the device. In other words, the poly hose is resistant to chemicals, whereas the internal piston pump design is durable. The list may go on with the stainless tank frame and poly lined stainless steel wand. At the same time, the seals are made from high-quality Viton for a boost of durability and strength.

Without a doubt, the addition of the built-in agitator ensures that the solution remains well-mixed, at all times. Plus, you can use the sprayer with an extensive range of solutions, such as powder, liquid and water-soluble solution.

The design is quite practical, as well. In fact, after testing the unit repeatedly, we can assure you that we didn’t experience back pain or fatigue. That is thanks to the breathable, padded nylon harness.

Its main purpose is to distribute the weight evenly across the shoulders. Concurrently, it facilitates lumbar support, which is very important. In fact, it is one of the most comfortable units we’ve tested so far.

Moreover, the patented pump design features few high-wear elements. This means that you don’t have to worry about making replacements since the mechanism of this sprayer is surprisingly durable.

What Others Say

As a rule of thumb, we always look for trustworthy customer feedback and reviews. This way, we find out about a product’s potential weaknesses, so that we know what to expect. So, what did we find after reading customer reviews for this sprayer?

Most people claimed that the item is well worth the investment, as it provides an excellent operation.

At the same time, the comfort element was mentioned by numerous reviewers. As we already said, the sprayer has an efficient, practical design, easing the pressure exercised on the back.

Nevertheless, since it has a manual operation, this doesn’t make it the most convenient backpack sprayer.

What We Liked

There are numerous things we enjoyed about this unit. We had high expectations of it, and we weren’t disappointed, for the most part. To us, the most notable advantage is that it offers good value for the money.

There are other products on the market within the same price range whose performance isn’t as good. Durability is another advantage since most parts of the unit are resistant to corrosion.

Of course, the harness system is also worth mentioning. And we’re not the only ones to say that – some reviewers outlined this feature, as well. Concurrently, the wand is responsive, not to mention that the pressure is consistent.

What We Didn’t Like

Moving on to disadvantages, there isn’t much to mention in this area. Since the device is manually operated, this could make it slightly inconvenient and annoying to continually pump the liquid.

Aside from that, we would say that this is a good product overall.

Buying Advice

We got this product from Amazon, and at the time of the purchase, we obtained a 13 percent discount. Although it might not seem like a lot, it still counts, in the long run. Plus, the shipping was free.

Final Verdict

On the whole, if you’re considering investing in a high-quality backpack sprayer for a medium or large-sized property, the Smith Performance Sprayers NL-400 Backpack Sprayer might be the right one for you. Still, although it is an excellent product, bear in mind that it has a manual operation.

To that end, if you consider convenience to be a priority, a motorized item might be better fitted for you. Feel free to have a look at other reviews you can find on the site so that you make a fully informed decision!
