The keon is awful, doesnt compare to the handy.
But saying that the handy requires you to build a handsfree mount for it to be anywhere near as immersive as the keon is out of the box, but if you do its the far superior toy.
Grab an ikea 3 leg stool but only attach 1 leg, and a set of stanley vice grips. Works awesome when laying down, sitting or in a recliner arm chair.
