I'm really sorry for the OP that you went through this... I'd be exploding from the head in anger LOL. But I'm also very interested in what materials you are using and pictures of how you set up the RHP's. Having two RHP's fail in the exact same way makes me think there might be something else going on with your particular case, even though I'm sure reptilebasics have had bad products in the past.
The BOI thread would be the most reliable.
