  • Just what I needed
Size: Single Pack (10.1oz)
No issues. Product came as advertised.

  • Cheaper than most others, but high quality
Size: 16 Pack (10.1oz/canister)
Lays super thick, and after it dries, you can feel how firm it is. It won't fill gaps and hold over old caulk, but this is really good quality caulking after trying other more expensive brands. Especially at the price range per tube, it is pretty good. I would definitely buy again. I seen several reviews of people saying it doesn't work good, but they probably can't find their way out of a box. This is good quality caulk. ... show more

  • $80 down the drain
Size: 16 Pack (10.1oz/canister)
I literally hate this stuff. It is so messy, EVEN WITH GLOVES ON. This crap smears everywhere because the “sets up in 30 mins” is a straight lie. Maybe 30 months. Another lie, “pinch a hole” in the dispenser…I just about had to go get a saw to cut the top off. Then you have to use the nozzle provided that has a hole already. That hole is way too big. I don’t understand. You can always make the hole bigger but never smaller, so why is it so large? I tried to use it in between some tile, as it clearly states you can, and it stained my tile, immediately. I did not let it sit. Also, so much comes out of that big hole that I couldn’t put a smaller bead, so there is no way I’d be able to fix this issue. Thank the Lord I started on a few tile that are not going to be seen. However, construction was delayed and I didn’t get to start the flooring until 22 March so of course my return window ended 19 March. Now I have 15 1/2 tubes of this messy junk. I don’t even know anyone that I dislike enough to give it to. $80 blown away like it never existed. I don’t know about you but in this economy I don’t have the luxury of wasting that much money. Needless to say, I will never purchase from this company again. Oh, and if anyone out there still wants to try this stuff, hit me up. I have a good deal for you. ... show more
