Upon unboxing the first thing I noticed was it's incredible fragility. None of the electronics were
housed in any kind of protection. Tiny exposed wiring and transistors. The printed instructions left
much to be desired and the video tutorial is useless. Neither of them go into any detail. To top it
all off, it never worked. I tried charging it with the also extremely fragile board and adapter and
changed the button batteries in the remote switch but nothing ever worked. The concept is brilliant
but the devices need much improvement. I returned this item.
