Review: 40311 Lego Xtra Traffic Lights Polybag

A few weeks ago Lego Xtra polybags debuted in Lego stores in Europe.  Looks like they've finally made it to the United States.

Bag.  I paid $3.99, for a $0.09 Price per Piece.

Instructions.

Parts.  Plenty of New Headlight Bricks.  I
think those Bar w/2x2 Base are new.  Tons
of 1x1 Round Plates.  The Minifig Bottle
could be handy.  Tile Clips, Tooth Plates,
Dish, and new Leaves should be useful too.

Build.  The proverbial Glass Cannon frame, 2Rd.

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.  (+5)  (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: +10 (A-).  Seems like a fitting score for a parts pack.
