I used to use it, as I heard it did a great job protecting from rust and I saw that guy's test that was done on the various protectants. Long story short, I noticed one of my long term storage guns had some surface rust on it, so I stopped using Eezox. I had a similar experience with Renaissance wax, but most people seem to swear by it. I won't store my guns with that anymore...
For long term storage, I use Frog Lube, or Riggs grease. I've not had any issues with either of those products. I also use Corrosion X a lot these days to clean (including the bore) and wipe down/protect my guns. I'm really happy with its performance, as well, and have not seen any signs of rust from storage. I found out about from some of the long range rifle shooters at my club.
