Very handy device, otherwise I initially would not know what I was looking at.
No tactile/audible feedback with the buttons (bummer). Wish they could use dlp tech to create a constellation overlay in a viewfinder...but I guess they would call that a "delux" personal planetarium then.....
Cons: Learning the control functions, no tactile/audible feedback.
