I have used the name brand gun (Great Stuff) and foam cans as well as multiple "clone" or aftermarket types of spray foam guns and different brands and types of "pro" spray foam cans. The GrizzlyGuard Spray Foam Dispensing Gun is very typical of the multiple brands of aftermarket dispensing guns available online, and all are at a much lower price point than the Great Stuff "name brand" dispensing gun from the local big box stores. The 2 main functionality differences are the inclusion of a shut-off valve where the can attaches to the gun, and the shape of the tip at the end of the gun. The Great Stuff gun does not have the shut-off valve and has a smooth tip end instead of the barbed style tip of the aftermarket guns. The barb style tip allows for attachment of various plastic extension tubes, nozzle tips, and fan spray tips. This GrizzlyGuard Spray Foam Dispensing Gun works fine as do all the similar "generic" guns I have used. As long as you clean it properly and promptly after each use, they all have done the job just fine. The nice thing about the "cheap" generic spray foam guns, is that when you forget to clean it promptly or something unexpected happens and you don't get back to finish that can left on the gun when expected - and the foam leaks or hardens in the gun - then you are only out the price of a $20 gun instead of $70 for the name brand gun. At the time of this review, the GrizzlyGuard Spray Foam Dispensing Gun is priced a bit over over other similar options, but still way under the name brand gun - so can't hurt to check prices when you need to order that next new spray foam gun.

I had a gap in my front door and I got tired of shoving plastic to keep air and bugs out of my home. I decided to foam insulate it and use this gun to do it. The gun gets the job done but it probably was overkill for my job. It is probably best when you need to walk down a long crack or run. However, it operated smoothly and without issue. I do need to research on where to get more nozzles though. Also, be mindful of which cans you buy to use with it. You'll need a compatible size to fit into the gun. Very easy to use and good value for your budget and hands! LOL!

Tips should be screw on.

This is a decent spray foam gun with very limited accessories. It will get you through a few projects as a home owner without issue. It is adjustable as to flow rate and output characteristics by both the trigger and the knob at the rear which limits the triggers maximum position. The trigger is controllable and the valve is at the end of the metal tip. This minimizes the foam from expanding out and making a mess between applications. Also, this valve prevents the foam inside the barrel from hardening over a few days.As far as price goes, it is currently listed at $29.99 each with few accessories. An identical spray gun, except for color, can be bought for $19.49 each with more accessories (Amazon item B0CR1SW2CC)...just search using that code.

Gun works great for spray foam canisters. Well-made and durable metal construction. Comes with an assortment of plastic tips
