### ⭐⭐⭐⭐⭐ It arrived dried out and hard as a rock
*by T***0 on March 5, 2024*

Really disappointed in this purchase. I though I was buying from a good manufacturer but this tube of caulk was totally dried out. I snipped the tip off, tried to get some product out, nothing came out. I put a nail in the tube. Hard. I contacted Amazon and asked for a replacement as i really need this product to seal up some gaps around my Lanai. Amazon replaced the item and didn't ask me to send the defective one back. Gotta love that service. The replacement will arrive tomorrow. Hope it is better that the first.Update: The replacement caulk arrived from Amazon today as promissed. I applied it this morning and all worked perfectly. The caulk is just the right consistency to hold shape and be smoothed with a finger. thanks Amazon for making this purchase work for me.

### ⭐⭐⭐⭐⭐ Excellent caulk!
*by A***E on October 10, 2023*

This is the first time I tired this brand and i'm happy to report it went on wonderfully. 100% silicone is the way to go for any outdoor caulking needs. I've tried other brands who sell 100% silicone and have had good luck with them as well but this was at a MUCH better price. This color matches well to brown metal siding.
