First things first: note that the special text of this site is _not_ the same as for the hero version. In some ways, it is better. Unlike the Hero version, the Minion version is somewhat more useful.
Next, note that the company must be covert. The first time I saw this site used (in the MELE sealed deck at Origins), my opponent used a troll to pitch a couple of trophies to make items playable. This is not legal. Clever, but sadly not legal since Orcs and Trolls are the only ones who may take trophies and they are always overt. This is some good advice also: if your opponent uses a card you have never used yourself, always make sure you know exactly what it does
However, the ability to make any gold ring at all playable regardless of normal playability restrictions is quite a bonus. Perfect Gold Rings are especially reccomended, since the dragon's lair requirement is pretty harsh. Bright Gold Rings are also good to play here since Free-Holds can be pretty scary. On the other hand, Gleaming Gold Rings have better place (like Dale) to fetch from. While the Ruins & Lairs does open up a number of nasty hazards, the site path to Hermit's Hill is pretty bening, the auto-attack is really wussy, and the card draw is only 1. It isn't absolute safety, but it is one of the safer places to get rings.
The question is, of course, whether it's worth pitching 2 minor items to use this site -- and that's a pretty tough call. In general, minor items are useful enough to keep around once you have them but unlikely to be worth putting in your deck, However, it's certainly worth considering putting an Old Cache or Swag in your deck if you are tracking down rings.
In my opinion, though, unless you have seveal Perfect or Bright Gold Rings in your deck, you covert companies will probably have better placed to try to find rings than Hermit's Hill. The problem is that minor items are still just too difficult to bring on, and the two minor items you start with are likely to be too valuable to just pitch.
