FIRSTINFO A1638 (3rd Gen) Patented Lightweight Max. Pressure 140psi / 620ml Thickened Aluminum Canister Refillable Aerosol Spray Can | Compressed Air Sprayer | Wide Mist Spray

Follow-up: the vendor reached out to me after posting the review below. Without any questions, they offered to send me a replacement which I accepted. This was well after the return period had ended. They did not ask me to edit my review, or for anything.I have two of these: one full of WD40 and the other full of acetone. Turns out they aren’t compatible with acetone, and that’s the one that failed. They sent me a new one anyway. These people got my respect.——ORIGINAL CONTENT——-I got two of these. They get occasional use. One quit working after about 3 months. It holds pressure fine, but will not spray. I’ve replaced the nozzle, so something inside the mechanism must’ve gone bad. Durability is questionable. It’s too bad, because I liked it while it worked. Be cautious.

This is one of the tools you don't think you really need. Turns out it's a real money saver. And works way better than an aerosol can.Use it for Kroil penetrant. This stuff is pretty good. Much better than WD40 but is obscenely priced in aerosol cans. Purchase in gallon container greatly reduces the price. Still expensive, but it helps.This device works perfectly. A little tricky to fill but charges instantly and super easy to use. One quick air blast to charge lasts a long time. Great range for hard-to-reach items. Easy to control for close up items.

Works great, many useful attachments and holds pressure for very long time. Gallon of WD-40 was only 30$ and savee money over time. Only gave it 4 star because there is no safety lock and if you put it not carefully trigger could be pushed by something and cause accidental sprays, so wish it had security lock for trigger

The rubber O rings started coming a part after only 1 week of use.

The can is well made and tough. The aluminum pressure vessels is extremely thick (1/8" thick?) among well-suited to being pressured. The spray steam goes 15 to 20 feet and maintians the solid stream of liquid. However, none of the fittings could create a misting spray. I may have missed something in the item's description but I felt that misting certainly be an option.Having said that, I would be remiss if I didn't say the the can is very well built and should last for a very, very long time. .

This is a very good refillable spray bottle. It has a very practical capacity of 21 ounces, which I fill to 16 ounces. That gives me a pint of liquid to use and the bottle begins with 24% compressed air for pushing it out. I think that's a really good ratio to work with. If you fill with too much liquid you will be adding air several times before you use it. I think the bottle was designed based on a pint of liquid. Also the bottle is tall instead of wide. That 21 oz. container is very easy to grip and the trigger is easily reached. Add the versatility of being able to have a strong directed spray and a typical wide spray from the same container with just a flip and you truly have a winner in my book!

Excellent for lubricant. I buy Kroil by the gallon and save a ton over using cans. Plus you don't waste half the can that won't spray all the product out.

I really like the overall design thought and make of the canister and head. The unit is manufactured and functions well, maintains pressure well.The problem I have is with the nozzle setup. Subpar design thought and make to serve as a nozzle for a setup of this caliber. Very cheap plastic swivel mechanism. One drop of this canister and you can kiss the nozzle goodbye. The manufacturer does make a few aluminum tips but neither come with this unit. They must be purchased separately and they are way overpriced for what they are.If the manufacturer would revisit the drawing table over this nozzle arrangement, this would be a 10 out of 10 little unit
