T-Rex's Fuel Tank Chameleon is indeed built like a tank - the casing is metal and very sturdy, and the whole unit carries a considerable weight to it. This could be a downside if you are looking to keep a very light rig.
The unit's power is completely clean and having several separate isolated outputs is definitely a bonus, and much more so than others in its price range.
It includes more adapter cables than you could need with it, including a voltage doubler and some different types of adapter for odd or vintage pedals.
A downside is that the only included power cable is for EU-style 2 pin sockets, meaning that I had to go and buy my own one separately.
Another problem is that although it fits nicely underneath, it does not fit with the brackets that come with my Pedaltrain board, thus it is currently stuck on to the bottom with velcro, which I do not necessarily trust with heavy use.
These two points are rather minor, though, for a PSU that does its job and is built very well.
