Wal Mart's Super Tech DEF?

Has anyone used the Wal Mart brand Super Tech DEF? If so, opinions?

Haven't used WAlly brand but I did use another cheap brand. I got repeated check engine lights for insufficient catalyst on a run to Minnesota and back. After that I drained the DEF tank and refilled with Peak Blue DEF. I haven't had a CEL since then.

It could be coincidence, but the few $$ savings isn't worth it to me now.
