This toy is similar to popular music or band builder kids software applications available on some tablets, but has added advantages of being very durable and more interactive. Once the base is turned on and in music mode, you can select different instrument pods and insert them into the arms, and they immediately jump into the current song and begin to play. We had kids between 2-6 years old playing on it, and all were able to quickly pick up how it worked, and all enjoyed plugging in different combinations of instruments to add them to the song and see what the result was. It's advertised for 3-6 year old kids, but I think is probably better for 2-4 year olds, though older kids that have an interest in music and musical instruments will still enjoy. This was one electronic toy where I was actually wishing the volume went a little higher! This is a great toy for 1-3 kids to share and collaboratively build songs with.
Some other thoughts:
Setup - super easy, batteries included, just remove from packaging and play. I was able to get it from the box to playable within 30-60 seconds without scissors or anything else.
Design - With a cool design and lots of colors and lighting, it is pretty good. The instrument pods are numerous and there is only storage for 2 built into the base, so do be prepared to have instrument pods rolling all over.
Durability - Seems pretty kid-proof, except for a little shelf that attaches to rear and holds 2 instrument pods. I think this shelf is optional, and I suspect it will get taken off at some point and lost. The instrument pods are a simple mechanical design with no electronics or batteries themselves, so nothing that can get easily broken by water/drops/etc.
Sound - No annoying repeating sounds, musical tracks are good, and volume is fine if not a little too soft. [This review was collected as part of a promotion.]
