I tried this mod yesterday and I must say I prefer my lapbook with the metal bar. When the screen is at its maximum open position, it doesn’t sit firmly in place, the slightest breeze will move it. I’d like to point out the device does not tip over but it will sit balanced between the rear feet and the bottom of the screen. If I used it as a mobile companion I might consider it, but as a device I will use 99% at home, I prefer it to be more stable and rigid at the cost of about 150 grams more (1350 gr VS 1500 gr). Still, good to know I have the option!
