Best On the Market

Excellent product, but like all silicone, caulk or adhesive tube products, be careful that the vendor doesn't send you a product that is old, expired, or half hardened.

Verified Purchase

Two products came instead of the one ordered

I initially ordered one tube Silka Flex from Walmart thinking it would be a fair price and get here in a Timely manner. They ended up sending me two tubes of sofa Flex at $27.97 a piece. I went to Lowe's after I used the product and found out it was only $16 and change. I tried to get it changed back to one tube but they sent me to and the person at Walmart assured me that it would be corrected before it got to me but it wasn't. It was shortly after this debate on The Soca Flex at the customer service office that I discovered that my debit card had been hacked and I had to stop it.
