They may be made better now, but I didn't like the smell the VE's and their predecessors put off, and I didn't like the taller construction. In an exo terra a VE would probably blend in better. In a PVC enclosure since the Pro Products are only 1" tall you won't see it unless look up under the lip of the enclosure. At least, I don't see them in my enclosures unless I bend down and look.

You probably can't go wrong with either. My experience with Pro Products panels vs. VE, helix, etc. has made me a believer in their product. I was lucky to have a local friend who has over a dozen of them in use so I was able to really check them out before committing to buying.
