@Tdaman,

Guess you don’t know then, Mr. Installer, that Coretec has pulled its Advanced Plus line–in simple words, the new tech they had hope was giving customers an advanced look and performance was leading to problems w/ the locking mechanisms and with cupping. So many complaints from customers and retailers have caused them to stop making it for a time.

Unfortunately, there are many people who purchased it from retailers who are not letting them know about the problems.
