Purity: Crystal Blocks (#4) Plane Review

Here's the last one for this week.

Box.  I paid $4.99, for a $0.15 Price per Piece.

Instructions.

Parts.  Plates, Wedge Plates, Grille Tile, Studless Slopes, Round Tiles,
Slope, Bricks w/Studs on 2 Sides, Minifig Telescopes, and Brackets.

Build.  Another IO frigate.

  

The Questions:

Can you build something -- a frame, station, or starship -- right away?  Yes.  (+5)
Is it below, at, or above the golden ratio?  Below.  (-10)  (The Golden Ratio is $0.10 per part.)
If you can't build a frame right away, or choose not to, does it have parts you should be able to put into use right away?  Yes.  (+5)
Does it have more than a handful of immediately useful parts?  No.  (-5)
Score: -5 (B-).  Not great but might be useful if combined with another set.
