I am a Helix user and have been for almost 5 yrs now. Never had a problem w/ it. First used it on a cage then moved it over to my rack. Worked great in both situations.
Helix or Herpstat are both good. I guess it is a personal choice. Both do the trick well.
From my limited experience it seems to me most larger breeders use Helix. Like I said that is from my own personal observations.
