I love the idea! They look great. Theyre convenient. Easy to use. Just don't last very well. My son bought some then dragged his feet while playing and they snapped (totally his fault) so he got some more for Christmas  and it is mid March and probably half of them have broken, just snapping one at a time as hes going about his day Hes not rambunctious or particularly hard on anything, they just aren't lasting very well.  We are very disappointed, they are such a cool product!
