Purity: Kre-O 80714 Transformers Battlechangers Megatron Review

I stumbled across a bunch of Kre-O sets I didn't own when wandering through a Dollar General store recently.

Box.  Base price was $12.00 at Dollar General, for a $0.16 Price per Piece.

Instructions.

Stickers.

Parts.  Lots of Translucent Purple.  Slopes, Plates, Wedge Plates, Ball Joints, Clip Plates, Bar Plates, Lampholders, Modified Bricks, Grille Tiles, a Tile, and Kreon Parts.

Build.

The Questions:
Can you build something -- a frame, station, or starship -- right away?  Yes.  (+5)
Is it below, at, or above the golden ratio?  Above.  (-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?  Yes.  (+5)
Score: +5 (B+).  The price I paid kills the score a little bit but this still has good parts.
