Kwazar Mercury Pro+ 300 Sprayer Reviews

Filled it with adam's wheel cleaner and after a few months, it stopped working. I cleaned it out and then it started but it was only spraying a fraction of what if should have.

These are great sprayers. If you're having an issue with spraying, there is a small plastic bearing inside that maybe damaged or fell out if the sprayer head comes off. Simple fix was to buy some 3/16 to 1/4 inch stainless steel bearings from Home Depot. They will start spraying again. I've figured that out about 9 months ago and they have been working fine ever since.

I heard Kwazar bottles were good so I bought a few to fill the gap until I could get more of another brand I prefer. Can't say I like these at all. The double spray action rarely worked at all for me. First spray would be like 1/5 spray amount, second spray would be fine. Some days it would work fine, others not. The bottle itself feels really sturdy and better than something from Walmart but I would honestly rather use a Walmart bottle for a fraction of the price for my experience with these.

I've owned around 6 or 7 of these (bought all at once). They lasted for about 2 months before they completely stopped spraying. The y also constantly leaked and the sprayer head was always way too lose from the lower portion of the head. All in all, these are very low quality for the cost and have virtually no reliability. Id also add that they can't spray anything that is "foaming" and using iron remover in a bottle will destroy the metal tip they put on to weigh it down. What a waste of money. Very disappointing.

Great product. nozzle has wide array of spray patterns. Sprays in any angle. Wish there where dilution ratios on the bottle.

I was feeling optimistic about these bottles. The spray trigger is solid, the flat bottom is truly amazing.

I bought 2 to give them a whirl. After 6 days of use one no longer sprays. And the second unit the sprayer pops out from the screw in bezel. Im very disappointed especially at the price.

Very nice product. Quality. Solid build. I needed something for chemicals which kept eating through the bottle. This has been great.

love these sprayers ! durable, quality unit.

Quit working after two weeks. Would not stay primed and when it did start spraying, it would only spray on the pull. I did like it for the first two weeks though!

Very useful when you need to use a lot of product. Feel very high quality, but for the price you pay they should.

I actually took a chance buying this sprayer and I have no regrets. As a professional detailer, I've bought all kinds of spray bottles and a lot of triggers can cause hand fatigue. Kwazar 360 for the win. Seriously worth the investment. Wish there were more color options for different chemicals.

I was heasatant to purchase the Kwazar spray bottle 360 due to the price. I purchased a 500ml and a 1000ml to give it a try as I was interested in the double action trigger. That was 6 months ago from the day I received them, I've had acid base wheel cleaner in the 1000ml at all times the only time it doesn't have any in it it's because I ran out while detailing my customers vehicle and I immediately refill it at 4:1. Ihave never rinsed it out or the trigger and it still sprays like the day I took it out of the box. Needless to say I know own around 10-12 500ml & 1000ml of them total and just received a Kwazar pump foam spray that came yesterday. I haven't tried it yet but I have no doubt that it will work as described and be a great addition to my detailing business. Do yourself a favor and just purchase one if you're one the fence about it and I'll be willing to bet you'll be purchasing more after using it and seeing how well built. They are and just so awesome the double action trigger is at reducing hand and forearm fatigue.... I have tried many other brands styles shapes sizes and from my experience the Kwazar is in a different league and worth every penny. Even though they are pricey hands down its worth it.

The sprayer mechanism is awesome BUT unfortunately the 1L bottles are too heavy for the design and every single one has broken on me. The 500mL ones seem to be just right and not a single one has broken on me.

Love the 360 sprayer. Really saves time and more importantly, wear and tear on your hands and forearm.

Editing my review because I was able to fix the issue. Bottle quit spraying on the depress and only on the release. I think one of my roommates was playing with it, dropped it, and had the handle pop off. There is supposed to be a one-way valve in there which I think is simply a ball bearing. I replaced it with an airsoft BB and it works great again! Love this thing

Worked great until it didn't... Had the bottle for about 3 months or so and have used it with P21s Gel Wheel cleaner only. This past weekend, it quit spraying on the depress and was barely spitting anything out when you release the trigger. Not sure if the gel wheel cleaner is too thick for it or what, but I'm going to try and figure out how to fix it... The real answer for if I would buy it again or not is maybe. It's great for product you need to spray a lot of without getting a really fine mist.

Easy to use very handy.

Love these bottles. Makes spraying much quicker and reduces hand fatigue. That's not important for glass cleaner but means a lot for certain chemicals during a full correction.
