Although the music is slightly muffled, the lights and movement of this toy is pretty creative. I love that it has sensors to keep it from running into everything. This is a perfect toy for children with sensory issues. My Grandson (5) loves it! It's the first toy he grabs from the toy box!too bad it doesn't have a button to shut off the music, besides this good productSuch a fun and cute gift. I got it for my son and we both love it. The crab has sensors on his legs so it will go to the opposite side when you put your hand or something in front of the sensor. Also plugs in to recharge instead of batteries which is a huge bonus. Comes with the USB cord to charge. Great product especially for the price. Mine doesn't work to well on long carpet. However, haven't tried it yet when fully charged. Maybe it will work better on short carpet when it's fully charged. One of my go to toys!We got this for my 3 month old sun to do tummy time with. I love that it moves around so he has to turn his head in both directions. The recharging feature is nice as well, the less batteries to replace, the better! I do wish it worked on our carpet. I think this toy is well worth the money, as we can use it for tummy time and for when he starts crawling!I love this toy for how well it maneuvers and keeps the kids giggling. The only downside is the loudness of the legs on the ground and the music. It’s the same tone continuously and I had to put on the “hidden toys” shelf for a while. Other than that, great toy! Better for large rooms or outside on solid concrete. I would suggest to the maker to put rubber on the bottoms for sound dampening and for traction. 10/10My baby liked to just hold it up and watch it jiggle it’s legs all loud like a spider but it also works great for tummy time and stretching her head left and right. It does die pretty quick and it likes to back up as it runs so maybe to your tummy time by an edge where it can just run left and right instead of running away for goodIt is going to be a great Christmas gift for my grandson.
