Easy to use and carry; the provided handling is good and you're bound to come up with your own if
you mess around.
Only con is that there is no info provided on best way to replace the
ball! They're super easy to lose (or give away to a kid/drunk adult) and I have to track down an
exact match for the gimmick online. Most products that are similar also come with a variety of
colors, too, so you pay more for stuff you don't need. Wish Penguin would've made them all the same
color and sold refills or something; they were so (maybe too..?) thorough with everything else that
this seems a silly oversight.
...none of that is Kranzo's problem/fault though, and has
nothing to do with this is fun quickie that accomplishes the same goals more expensive/difficult
effects tackle. Perfect visual and lighthearted effect for the "do a trick" moments or other casual
situations.
