If you don't particularly plan to use this thing by the pool or on the beach, you can opt for the cheaper variant that's going for $19.99, down from a regular price of $99.99. With up to 12 hours of playtime from a single charge, it doesn't last quite as long, but again, you're getting this for nearly half the cost of the aforementioned option. This model is available in your choice of black, green, or red. You can also get it in blue or gray, but those colors are only reduced to $34.99.
