I’ve fed both Dumor and standlee. Both are hard and take a while to soak, though it my experience Dumor is a little softer. I’ve found pieces of hay string in both and both at times don’t look the prettiest. I think it’s 6 of one, half dozen of the other. The best I e seen are Seminole cubes and they aren’t local to me. 

I guess everyone has good/bad experiences with each. When I stopped at Tractor Supply yesterday they were out of Dumor so Standlee it was LOL 

I soaked them some but my mare seemed to prefer having some firmness to them. She wasn't super crazy about the mushy stuff. 

I feed them daily soaked.  When snow storm was going to hit I stopped at TSC and they were out of the Dumor cubes so I got a bag of Standlee cubes.  They were horrible.  Horses did not like them at all.

The Dumor sure soaks better than Standlee. You better have all day if you need to soak a Standlee!?? I found Mustang Sally cubes local and they are even softer. These don't even need to be soaked.
