[This review was collected as part of a promotion.] Great Stuff is an amazing expanding foam product for many projects around your home and garage.  From those tiny cracks to holes in the wall. This will take care of filling it and you won't have to worry about it anymore.  It's worked very well for us.

Always great!

[This review was collected as part of a promotion.] Before the use of this product I was bothered by small insects getting into my home through cracks left around plumbing and other places, since the use of this product I have noticed less and less pest inside my home.  Thanks much !

Wonderful invention!

[This review was collected as part of a promotion.] I received GREAT STUFF SMART DISPENSER Gaps & Cracks recently and this stuff is incredible. Ever since I moved into my new house my shower has this problem with leaking from certain areas because the previous owners did a poor job installing it and nothing I've tried in the past 3 years has resolved this problem, until now! This stuff is super easy to use, it dries quickly with no messy residue and it really works. It's been a couple weeks now and my problem has FINALLY been resolved thanks to GREAT STUFF SMART DISPENSER Gaps & Cracks. I would highly, highly recommend this for around anyone's house!!

Awesome product!

[This review was collected as part of a promotion.] I was recently noticing some ants coming in through some cracks by the door.  It was really stressing me out.  And then suddenly soon after I stumbled upon this product and it was exactly what I needed, now the ants no longer enter my home by cracks.  It also does wonders around windows.  5 stars.

fills cracks

[This review was collected as part of a promotion.] I'm not very handy, so I was excited to see what this product was all about. 
There was a postcard inside with tips to help to learn how to use this properly and keep it working efficiently, which is handy because I learn best through pictures and simple explanations. I've been able to fix small cracks and gaps around my home and keep it looking nice. I'm very satisfied to be able to fix these small issues before they get worse and I have to spend a bunch of money. The smart dispenser is super convenient, and the product doesn't spurt out, it dispenses smoothly.

Easy to use

[This review was collected as part of a promotion.] This filler is the easiest I have ever used! The straw is so precise, and it stops dispensing when you release the trigger. I would recommend it to any one especially for small jobs. I'll never use any other filler.

"Smart"

[This review was collected as part of a promotion.] This Great Stuff insulating foam sealant is so easy to use and perfect for sealing holes and cracks to prevent heat loss. The winters get bitter here in the Northeast and this is such an easy fix for those small holes that let that cold air in! This quickly fills the gap and is water-resistant. Great for filling gaps around pipes as well as keeping out the rodents who love to seek shelter from the cold. Such as inexpensive great value item!

Great for reducing drafts and saving heat loss!

[This review was collected as part of a promotion.] This stuff works great! We used it on the outside of our house at our air conditioning drain. It worked well to seal the open area between the pipe and our vinyl siding. It was easy to use and worked great!

Works great!

[This review was collected as part of a promotion.] I received this product as a sample I was happy with this product it worked will for me I used it in my bathroom and it did just fine.I would recommend this product to my family and friends thanks for choosing me to try this product out.

Good product

[This review was collected as part of a promotion.] Used this product and I am not very happy with the application trigger device. The foam product itself is awesome, but the trigger that you use to apply this foam into gaps and cracks isn't. The trigger device comes off the spout whenever you release pressure on it and the stuff goes all over your hand. Again the product itself is awesome, just trying to use it with the trigger device can be tricky,
