Redstone Box (a.k.a. Melting Block) is Creative Crafthouse's version of this classic packing puzzle designed by Thomas O`Beirne. The folks at Creative Crafthouse were kind enough to send me a copy to review. Thanks!
This puzzle uses a commonly used principle whereby a tiny amount of wiggle room in the initial configuration can be 'collected' (by rearranging the pieces) into one spot that is big enough to contain the target piece. Of course, even if you know the principle, this can be quite tricky in practice!
Kevin mentions in his blog entry, even after solving it once it can be a good challenge to do it again. Allard also posted a review here.

I would imagine that the fit issue was just a problem with my particular copy of the puzzle, and generally won't be an issue. If you do, I'm sure they would let you exchange it per their returns policy. [Update: Dave from Creative Crafthouse said that this is the first reported incident of the cover being too tight]. Aside from that issue, the quality of the puzzle is good, with a smooth finish and nicely beveled pieces. Some folks may not like that the red piece is stained rather than a natural wood color, but I think it makes it pop nicely. The stain lets the grain of the wood show through, so is much better than paint. Overall, Redstone Box is a fun puzzle that is worth checking out!
