I picked this set up back before Christmas at my local Five Below. The Hasbro website has it for $7.99. I got it for $4.00. It has 75 pieces.
Instructions and stickers.
I see 1x4 Hinge Plates, 1x2 Trans-Red Plates, 2x2 cheese slope and plate combos, a couple of 1x1 bricks that are only two plates tall, a bunch of 1x1 round tiles that have writing on them and are slightly larger than 1x1, and a couple of pieces that look like a 2x2-2x2 Bracket combined with a Hinge Plate. That's a real smorgasbord.
In this picture we see the Kre-O ball joints. They're nice and sturdy but have this rubberized coating that makes them very stiff to move. Not a great trade-off. The head is interesting too, as it attaches to the 2x2 plate with the pole in the middle.
Here's the first frame I built with this set. Pretty bulky, it could be statted up as 2Rh+d8/2B/2W.
Here's a station too. Once again, not that great but it's using pieces. I still have a handful of plates left over.
Can you build a frame, or frames, right away? Yes. (+5)
Is it below, at, or above the golden ratio? At normal price, above. (-10) ($0.11 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+). If you can get it on sale like I did it jumps to a A+.
