What’s everyone’s opinion on the spillers ulca balancer?

One of mine has a small amount of it, he seems to like it? I balance that out vs his supplements so can reduce those when he’s on it.
 
I used the UlsaKind cubes from topspec on my mare who had ulcers and stressed so wouldn'tput any weight on. I found the cubes helped amazingly at putting weight on her but not a huge fan of Topspec as there's a lot of biproducts in there.
