My German Shepherd loves it!
Color: Blue
My GSD loves this thing! It bounces and the rope thing wiggles and spins. She is supervised while playing with it. The charge lasts about an hour or so. The only thing that is a little annoying is it makes a little barking sound on one of the settings. It screws apart for easy access. So far she's not been able to destroy it but she has opened it so definitely supervise playing time. It rolls around and bounces on the carpet and on the hard floor it jumps a little bit. Can be loud on hard floors. It's a soft rubber kinda texture that is easy to rinse off and clean. Probably best for indoor use or use on decks or patios. Keeps her very engaged and I have a blast watching her and playing with her with this thing!

Not for chewers
Color: Blue, Color: Blue
Ok, first off, my dog absolutely loved this toy. Still loves it. However: it only took him two days to utterly destroy the part that made it interactive. The rope fastened to the small interior plastic part that is moved by the rechargeable motor was too soft for him and he chewed it off right at the root, where it attached. This makes the toy immobile. It still makes noise and vibrates, but it no longer leaps and bounces. So now he carries it around while it vibrates inside his jaws and I watch his ears jiggle and make sure he doesn’t eat the whole thing. Please note: this is a medium sized Corgi, not a huge dog like a Rottweiler. There is no way to add a new rope to that interior plastic piece: they are made as an inseparable unit. You have to buy the full replacement set which includes a new cover. I would recommend this toy for someone whose dog is NOT a chewer. For someone whose dog loves to chase, and is excited by noise. If those pesky squirrels chattering outside really get to him, this toy will be his new favorite. But if your dog likes to chew and has more than two teeth in his mouth, this toy is not a great choice and you should spend your money on something that will last a bit longer. It’s not a good value for the money. I bought this original toy and a replacement cover+rope set, and I’m not going to give him the replacement cover for a long, long time. I can’t afford to replace these every few days! Thankfully he still loves the toy despite the fact that it doesn’t run away from him, and hasn’t tried to eat the foam covering, so it’s just the softness of the rope I am disappointed in. But I’m not going to buy this again and can’t recommend it highly, based on my experience, despite my dog loving it and the joy I get watching his ears shake as he trots around the house holding onto this expensive mouth vibrator.

Not worth it - (2nd day of having product)
Color: Orange
Fun toy out of the box - Frenchie dog. Charge does not last long. Even with recharging, the motor seems weaker. It asks to keep the charging port dry, but it is not slobber-proof, so when opened, the entire inside is wet - I have to blow-dry the charging port in order to be able to recharge it Day 2 - movement is so weak, but it shows full charge. Barking sound is no longer audible. If you have a chewer... not great as it is easily broken apart. Not really worth it. At least it's cheaper on Amazon than their website.

Interactive Dog Toy
Color: Orange
My 100 lb shephard/golden mix likes this toy but she tends to get agitated with it. I have to keep an eye on her because she destroys toys in record time. The only complaint I really have is once she gets interested and plays for a long time it needs to be charged and she doesn't want me to take it to be charged. Wish the charge lasted a little longer or there were two of the inner parts so one could charge while she is playing with the second one. The plastic ball could be made of rubber so the teeth marks don't show up.
