This ball is so much fun for our 5 month old. He both chases it and lets it bounce in his mouth. This was after playing with it already for 10 minutes. The ball charges with a usb charger and lasts for a long time. I do take it away to keep the toy fresh and prevent him from just chewing on it. I will say the ball startles you a bit when it turns on in your hand. Happy with a different toy.

Extremely durable, highly recommended!!

Color: Orange

This ball was a game changer for us!! I rehomed an extremely needy 110 pound one and a half year-old male Rott. This ball has been keeping him engaged for hours giving a much-needed break to me.😜 it actually stays charged a lot longer than I thought it would, and so far he is not chewed through it at all, which is incredible to me!! I think I’m gonna order another one so that I can have one charging while he plays with one and then switch off with them.

A hit for Border Collies

Color: Blue

Our border collie loves this toy! Keeps him entertained and when he throws it down it doesn't break open. Going strong for a couple days so far.
