I got this product to help in my battle against my landlord special of an apartment and it DID NOT disappoint. From cracks around doors and windows that the light shined through to the seam under a sliding door and so much more, this product did the trick to seal up the drafty spots. It’s super easy to use and reuse. Unless you’re really looking for it you won’t even know it’s there and there’s no foul smell to it either. It sticks well to itself and to whatever you put it on. A little went a long way for me! 10/10 would (and probably will) get this product again.

Easy and clean application of this clear caulk. No gun required is a plus. Used on a kitchen sink that was leaking due to a need for new caulking. Worked out great and sink no longer leaks! Great price and shipped fast. Purchased a separate tool to help with excess. Would purchase again.

This is hands down the easiest to use. No need to use a caulking gun. The caulk comes out uniform and consistent. I sealed 2 bathrooms first then save it to use later for the last bathroom. The consistency remained the same. Cleanup was super easier and has been the fastest that I've completed sealing all the bathrooms. Would highly recommend.

We purchased this to fill gaps around our home and it worked so well. I was worried about and odor since we needed to use it indoors and after using it in several places, there still was NO smell!! If you’ve ever had to use a silicone caulk then you know that’s huge. We had used the General Electric brand prior and it smelled SO strongly. We purchased the clear silicone and it truly was clear. No grey or cloudy color once dried. The squeeze handle made it much easier to use compared to having to use a caulk gun or your fingers to squeeze the tube. We would definitely purchase this again for other projects around our home!
