Good toy
My dog really loves toys, technically he loves to kill toys. This toy is supposed to be chew proof but after 1 day my dog managed to pry it open where the Velcro is to hold the ball inside and rip the Velcro out. Now when he shakes it the plastic ball comes flying out so it had to be removed. It also gets super slimy after he chews on it. He still loves to chew and shake the toy itself so overall it was a good buy since I don’t have to spend most of my day walking through my house picking up stuffing that he has pulled out of his other toys. He is not a big dog by the way just a Boston terrier with stuffed animal issues lol.

My puppy loves this!!!
UPDATE: my puppy still loves this toy, but I’m not super impressed with the craftsmanship. The fabric around the Velcro started to fray after just a few days and within a week the Velcro was completely detached from the fabric. She’s still able to play with it for now though. I’ll probably end up taking the ball out of the inside and putting it into a different toy and I’ll just sew some Velcro on so I can open and close it. It does stay charged a long time and my puppy enjoys playing with it but the novelty wears off a lot quicker now that she’s had it a couple of weeks. She’s usually into it for about 5 min and then it just vibrates its way into a corner until I turn it off. My 4 month old chorkie (6 pounds) absolutely loves this toy! I was afraid it might scare her at first but no, as soon as we turned it on she was like “LET ME AT IT!!” We’ve only had a it a few days but so far, it’s been a godsend when we are eating dinner or working or other times when we can’t entertain her as much as we would like to. It wears her out too, and after playing with it for about 20 minutes, it’s nap time. So far the battery life has been great. I fully charged it when it arrived and 3 days later it still hasn’t needed to be charged, and she has played with it for about an hour a day, in 15-20 min increments. I like that it has Velcro instead of a zipper, I think it’s a lot safer. The initial “Hello” when you turn it on is kind of loud but other than that, the noises it makes aren’t super loud. It repeats back the things you say, which took me a while to figure out. My puppy hasn’t barked at it but if you have a barker just keep that in mind, it will basically double the barks. It feels like it’s made pretty well, and my dog is kind of an aggressive chewer (she’s a teething puppy so of course she is) but so far it’s held up really well and she hasn’t been able to get the Velcro undone and get to the ball in the middle but if you have a bigger dog they might be able to. The Velcro is pretty strong though. Overall, it’s super cute and it makes my puppy happy which makes me happy! I definitely recommend to anyone who has a puppy or a dog with a lot of energy and needs something to keep them occupied for a while. I will say, after about 30 minutes max, my puppy is kind of over it but that’s a lot longer than anything else has kept her attention so I consider that a win. If I remember, I will update after a month or so to say how it’s holding up as far as charging goes and the overall quality of the toy, but so far I’m super impressed.

Major flaw
My dog liked this, but the charging port part is at the perfect position for dog teeth to catch on (there's a very large indented part with the on/off switch and that), so after only about two weeks of play, the usb C port is ruined and the toy can no longer be charged. Larger dogs or very small dogs might have fewer issues. My dog is a miniature dachshund and he could pick up the toy by biting at that indented part. (Also that "hello" is incredibly grating and if I forgot to turn off the toy would sound hours later, like in the middle of the night when we're sleeping and then my dog wakes up and freaks out.)
