JOUNJIP Refillable Non Aerosol Compressed-Air Spray Bottle- Pressurized Sprayer, Aluminum Can Sprayer for Automotive, Cleaning and Lubrication- 16 oz (Empty Bottle), NOT an Air Duster

No problems, and it's working great with WD-40. Only fill it 3/4 or the pressure will decrease too fast. The extras are a nice touch, and are compatible with plenty of other canned sprayers too. I wish it came with a cap, but that's easy to grab from an empty disposable can.

Bought and thought we would use it more but haven’t much. Does work good though especially when a tip breaks off a can. Keeps you from having to toss it.

The sprayer works great and the fact it comes with extra o-rings for different chemicals is awesome. The one thing that is incorrect is saying it can be filled by a bicycle pump. It can not, the problem is when you try to remove the bicycle pump after filling. There is no way to unscrew or un-lever (depending on style of attachment) the fill valve fast enough to keep from losing all of the air pressure. The volume of compressed air the sprayer holds is so small that any loss at all just empties all the pressure. In fact, the only way to fill it is with a large compressor and an air chuck that you press into the fill valve. Thats fine except for having to run a huge compressor for several minutes to build up several gallons of 90 psi air in order to put a few cubic inches into the spray can.

I purchased this sprayer in October of 2024 so I could use a full can of disinfectant that had lost its propellant. At first the sprayer wouldn't hold pressure, leaking the charge of air slightly over time. However, after a few weeks of use, the sprayer stopped leaking air, and to date it holds pressure just fine. I suppose some part of its mechanism needed a break-in period for all the relevant parts to seat and seal properly. The sprayer works quite well for what I'm currently using it for... spraying disinfectant. The overall durability and capacity are adequate for what I'm currently using it for, but the spray nozzles could be a 'beefier' design. The only disadvantage I have observed is no protective cap provided to cover the sprayer nozzle, which could cause the nozzle to break off at the stem if the sprayer is dropped or knocked over... hence the four-star review. NOTE: To mitigate this possibility, I repurposed the cap from a used-up can of cooking oil spray, which fits over the sprayers neck perfectly. I used a 1-5/8" diameter hole saw to cut away the outer portion of the cap, leaving only the inner section which seats to the sprayers neck.

It clogs within 5 uses and start spitting instead of spraying

This thing was way cooler than I thought it would be. Came nicely boxed with instructions and 3 nozzles, extra tubes (the kind you always lose of your WD40 can) And extra O-rings. The 160z can is perfect size and the Schrader valve works well and comes with extra valve cores. I was pleasantly surprised. First fill was water to checked out the stream, mist and jet spray, with and without tube. I giggled with delight at each one. It dawned on me that this thing was made in the USA and it showed in Spades. Great product!

Loved the concept of compressed air instead of aerosol cans. I bought the base model as a baseline to see if it worked well. Two changes I’d make is put a pressure gauge to know I’m not too low or especially too high in pressure. I used it a couple of times for my woodworking project to spray non waxxed shellac with denatured alcohol mixture. I’m not sure using these chemicals was appropriate, but I was extremely careful to see if it worked. So the compressed air was good and it didn’t blow up on me. The only issue is the splatter. I used the misting nozzle and I couldn’t regulate it to have a perfect stream. Sometimes I’d turn can upside down and it would be an even spray. Before I buy better version or look for other topcaps, I’ll try with regular water and see if it continues to splatter. I had to go over my project with a brush to even it out, but I shouldn’t have to. That being said, the concept is great, but not sure if the splatter was due to defective mist cap or if this item is not intended for anything other than liquids the viscosity of water. I do a lot of woodworking projects and still searching for the right small sprayer for dewaxxed shellac/denatured alcohol sprayer applicator. I am not a fan of using HVLP sprayers or the process of cleaning them out for small projects. And aerosol cans add up in coat quickly.

I'm using this for ATF and acetone to use as penetrating oil.

The aerosol works very well just got round to using it now my clutch and brake cleaner aerosol has run out. I like the choice of nozzles and the packet of spare tubes Just been using it on a chainsaw I’m working on and it does a great job at getting into all the awkward nooks and crannies that chainsaws have I would definitely recommend it.

Looks well built, sturdy and feels like it will last a while.

Great product, extremely useful.

This is a great idea. The initial cost will soon be recouped through not repeatedly buying aerosols and buying solvents and lubricants in bulk works out much cheaper. I would recommend the use of a stirrup type cycle pump rather than a standard hand pump as it is much quicker and easier to reach the required pressure. I have used a compressor but it is really overkill and can overpressure the item if you are not careful. A stirrup type cycle pump is more than adequate. The extra valve inserts and tools are a bonus though I have used it for a while now without needing any replacement parts. Overall an excellent product that I would highly recommend.
