I This product works incredibly. This is so far above and beyond any hopeful expectation I could possibly muster. It never sputters or leaks due to the mechanism, sprays evenly until the can is completely emptied (bone dry). If I had this over the past several years, I can't even imagine how much money I'd save. Spray cans are a pain when they get toward the end. WOW - this is great!

This item is perfect! Attaching it to a spray can is impossible for me, but apparently not too difficult for those with normal hand strength. I’m still able to use it with my dominant hand, but my non-dominant can also use it effectively.

The price point is low enough that I can buy extras so I don’t have to worry about frequent interchanging. I get an appropriately strong spray that I can easily control. At this time I don’t have to be concerned about focusing the spray, but it would be too diffuse and widespread for detail work.

Makes using spray paint so much easier and cleaner. Can't believe it took me this long to learn this product was available. Also, price is much better than others. Works perfectly unless you accidentally twist the handle around while shaking

Don't angle the handle as you slide on the can - I broke first can because I pulled the red trigger accidentally while putting it on the can - Have used on half a dozen or more cans already - easy to reuse

This thing works great!! I didn’t want to buy a professional spray gun because I didn’t have the money, so I decided to try this. I am impressed beyond max! There is a technique to it, so watch some videos of professionals painting before trying. Overall a really great product.

Worked as described. Definitely will need to connect and disconnect as instructed to keep from breaking the gun. Other than that I think you could use these guns countless times. Trigger worked well with minimal pressure. Balanced and fit comfortably during use.

This is also an absolutely necessary adjunct to can spray painting. While a human finger tends to alter the angle of spray and making the flow somewhat inconsistent, this addition over the nozzle is not only ergonomic in handling but also makes the spray more consistent in the pattern and flow, the amount emanating from the nozzle is more uniform both in patten and area of coverage. It also alleviates finger fatigue. Great tool.

These are a great addition to any aerosol can with the right nozel as they allow for many benefits. First, they prevent from causing pain in your finger from pushing down the nozzles on the cans. Second, they allow for precision of pressure and release for the flow rate as you can very easily adjust your grip on the trigger steadily (this is very hard with a small nozzle and the tip of your finger). Third, the housing around the nozzle prevents a bit from the spray going to wide and getting on things you might not want. Super convenient and reusable, I've used the same one through at least 15 cans now with no issues.

At first I had a really hard time getting this to "slide" onto the top of the spray can the way the directions told you to because the base/grip is waaaaaaay too tight/small. Then I popped it on, the way the directions told you NOT to do, and it was totally fine. It gripped it great. I love that the trigger is longer which makes it less tiring for 1 finger, and much more comfortable for your whole hand. Also, I like that the base grip around the can is so tight, that way when you press the trigger, the can doesnt fall out. I purchase a cheaper Rustoleum brand trigger, and the base grip was so loose, everytime the trigger was pressed the can would fall out.

My most recent order of this spray accessory was to replace the one I have used many times but had misplaced. Of course I found it after I placed the order, but it is such a great tool that I decided to go ahead and keep the two new ones in addition to the one I already had. It really doesn't keep your spray hand from cramping, and keeps paint out of the fingernail that would have been pressing the nozzle directly. I truly think it results in a better, more even spray job. No complaints.

These things work wonders. I've seen reviews going both ways but thought I'd give them a shot. I was a bit concerned when I popped the lid off a can of Rust Oleum as the spray top is different than you typically find, but I slid this on and when it snapped into place the parts aligned perfectly. I experienced no fatigue at all while I painted 4 shutters and I really credit this with the nice even coat I put on. Buy these, they're good.

These are fantastic! We are repainting a lot of outdoor items and this product is so easy to use! Took me a bit of time to figure out the angle in which to put these on the cans, but once I did, they go on smoothly. I kept knocking the sprayer tip off the can until I put a VERY slight upward angle on the attachment and it all worked out great. I had a more difficult time getting the lid off the can than I did putting on the attachment! Am able to spend much more time painting now!

I was spraying a desk and the first can I went through was so annoying. Uneven spraying, drips, made my arm tired from holding down in weird positions. These arrived in time for the last two cans of spray paint, and it made a world of difference. So much easier to spray, WAY more consistent even coats, and didn't tire my arm. One of the red tops kept popping off one when I would shake the cans, but I just held it down every time I gave it a shake and it worked fine.

I use these can-guns on cans of spray paint and lithium grease, and no longer get soreness in my arms from spraying. I use lithium grease on my garage door springs, as well as on all moving parts on my garage door. These can-guns are easy to push and slide onto aerosol cans. I had no idea these can-guns existed until a professional painter told me about them.

I would rate this 10 stars if I could! Such a simple product, but it made my life so much easier when I was spray painting. Totally takes the stress out of your hand and makes the job so pleasurable instead of having a sore hand for days after you using a spray can. I would highly recommend this product!
