Excellent product, used in kitchen.
I bought this in black to seal between new countertops and the tiled backsplash I installed in my kitchen. I’ve done a lot of home renovation over the years and I was impressed with how this product worked. Very thick but easily workable. Dried to a matte black so it blended in with my black grout and countertops quite well. Clean up was easy with isopropyl alcohol. Normally I use the silicone sealers from the home improvement stores but I found this stuff was a lot easier to work with, especially the clean up end. It does give off an odor but gone once dried. I’ll be using it again in the future.

Great product for boats
Works well for boat. Fills in holes and seals well great value. Has a slight smell but is not bad. Easy to put on with a basic caulk gun.

Great product if you can use it in four weeks. Check Use by Date.
Really like the product. Works great. My issue is that the product I received had a use date of July 2025. Not much time to finish a kitchen and three bathrooms where this was to be used. I notified the seller and they sent replacement items at no charge. I appreciate the response, BUT sending product with a Use By date of Aug 2025 is not much of an improvement.

Seals
If you need black silicone this is it! Slight shrinking but looks great. Price wasn't terrible and it was packaged nicely.

Really good
I have used many different types of silicones traditionally I always use it for something involving a aquarium or vivarium I'm making not only does this stick very well dry very fast feel very smooth but for the price it is by far the best silicone I've ever used the only singular issue is how thick the cap is I got a hole through the cap probably not the way you're supposed to maybe I'm just missing something but it is perfect aside from that one thing which again I'm probably just missing something about

Definitely not odorless
Works very well, and dried nicely. Although in the description, it said odorless. Its definitely not odorless. Now im wandering how long the smell will last. Because ive used it for my most recent vivarium build. Hopefully the smell dissipates soon.
