Never had a Chimera product I didn't like and they don't show age too fast.
Now the "others" they look nice, but some of them don't stand up to teardown and reassembly more than a couple times without the rods bending or a seam tearing. (Photo-flex, Calumet). I think these products are fine if you are going to set it up and forget it.
I am a location shooter and only Chimera stand up to reassembly year after year..
