LOVE the glow ball when playing inside once the sun has gone down, or in dark winter evenings/morning. The re-bounce ball (blue specks) is great and bounces SO high. My pooch can't let it go and almost likes to chew it more than have it thrown during fetch.
Pros: Bounce super high and helps get the ball that extra distance when using it with the chuckit. Easy to clean (important for slobbering dogs)
Cons: SO good, people will steal from you. Get stuck under the couches or furniture because they are squeez-y
