Easy to use

Where has this been all my life? I'm a 50+ woman and was able to caulk my shower floor and vanity with ease. This pump action gives you so much control of the flow coming out. No more giant globs coming out and needing to use a roll of paper towels. This product is great!!

Nice & Easy

I watched the video before buying. (I am elderly handicapped.) I bought one of these last year to seal cracks around an exterior window from the inside. I used the whole can to go around the entire single window. I have never used caulk before, but this was simple and not messy. I noticed some cracks in old caulk around other windows this spring and bought some more for them. Wonderful.

Ease of use

Easy to use around windows. Would’ve worked better if I cut the tip at a 45 degree like it specifies! Will be doing that next time

Easy to use even for a first time caulker!

Ok, Id never caulked before so I wasnt sure how its supposed to work, but this was really easy! You just push the little thingy and it comes out in a ribbon. I thought I would need alot more than I did need, its good stuff!

So far so good

Until it rains heavily I won't know how it works, but it did fill in the cracks. Will write a full review after I confirm it did the job. I hope!

Not as expected

Per instructions, I attempted to slowly apply the content but it was by no means coming out as a continuing flow. It was in lumps no matter what I did, the end result to seal the leaking window allowed more rain than normal into our solarium. Today, I will use Gorilla Tape to seal the window, not what I wanted but the water is damaging the wood and our Spanish Tile. Very disappointed

Effective and Convenient

Works great and very convenient. Much easier to get into smaller spaces with this instead of using a caulking gun.
