$49.99 shipped? WOW!
I ordered 2 four packs of Knog Frog Look-a-Likes for the kids bike from this seller and they came in 2 days. They are decent and the kids love 'em.
Looks exactly like the MagicShine.
Probably the same battery that GeomanGear recalled, so charge it in terra coat flower pot with a lid...just in case.
