We acquired 4 of these (1 for each kid, and 1 for me) the packaging is pretty awesome, comes with everything you need and if you treat it all gently it will last a long time. Comes with a link so you can find out how to do all the tricks and stuff. I do highly suggest reading the directions and looking up the videos so you can insert the string properly, if you don’t you run the risk of damaging the strings and the device.
We did have to contact customer service for and issue with the strings...
