FWIW - Looks reasonable to me. Personally, I like the design, weight and price much better than a similar mentioned recently. It just makes more sense to a guy that once thought he splurged on a grate to bridge two rocks and never looked back. Fireplaces and rocks ;) are normally provided where I go though.

Funny thing is, that angle looks much like the triangle I often use to build a fire as well so thanks and good luck!
