I think my workplace has four of these carts now, they seem to work pretty well. Nicely made, moves around easily, cool status lights, gets the job done.
-30 iPads at once. Awesome.
-Charges them all independent of a computer
-Just 1 power cord
-Holds iPads securely
-Man this things expensive.
-Build quality is good, but not $2600 good.
-Status lights are on the BACK of the unit.. against the wall (usually)
-Cords are thick and stiff, and fit loosely in the iPads
