It switches out flat objects quite well and the entire unit doesn't take much pocket space. I like
that this device is portable and unassuming.
Besides being a switching device, it can be
used to make things appear or disappear. I appreciate this type of flexibility.
There is a
slight audible click/snap during the switch but it is easily covered (e.g., snapping the lid,
flicking it, etc).
The reset is easy, but needs to be done in private. I've done the reset
in front of laymen, but only during an offbeat, and not immediately after the routine.
I
find it best use the case as an incidental holder as opposed to: "look what this device can do".
I haven't had anyone try to pry it open - they just look inside and shake it; nothing ever
falls out.
