What I like: The balls are excellent. You get an extra one (4) and an extra shell (2).
What I
don't like: The shells don't appear identical to the balls, however unless you study them really
closely I don't think this will be an issue. The shells are made of plastic, but still seem well
made. For me they are more difficult to manipulate than the silicne coated shells of the Mirage
sets. Finally, like the Mirage balls they are on the small side. Fine for me, but possibly too small
for those with medium to large hands.
