Gets 3 stars because, like all the boards I could find, it is a weird size, either much too large or just slightly too small for all the breadboards I tried it against. In addition to being unable to properly fit any board I could find, it is also about a half-inch too short for many through-hole components. Other than that, it was what you'd expect from a lump of ABS - sturdy, but not too hard to drill/cut for the specific wires and gadgets that I put inside it.
