I'm already ordering my third frame, and colleagues are going to get theirs too. The frame looks very neat and elegent. The Raspberry Pi is still clearly visible, which gives this a nice technical, erm, touch. For better protection, get an additional Pibow CoupГ©(*).
The frame itself is easy to assemble and to mount to the touch display. You'll need your own screwdriver though. The instructions are clear, with only one exception: you need to unscrew the LCD converter board from the LCD backplate first, as otherwise the bottom frame plate cannot be slided into place. From there on, everything else is straightforward.
The display rotation to be set in /boot/config.txt is well described, albeit only online, and easy to do.
I would have liked the frame to be slightly more inclined, but the angle isn't that bad. However, I'm now stacking up my frames by putting them onto some small cardboard boxes. Maybe Pimoroni may come up with some neat color-matched perspex support?
A useful addition may be a Pibow coupГ© to give better protection to your Raspberry Pi.
(*) When using a coupГ© with the frame and you're using the dedicated short LCD-Raspberry Pi micro-USB cable, you need to leave out the bottom plate #0. Otherwise, the cable will be too short. In addition, you need M2.5x20 screws to fix the Raspberry Pi with the coupГ© to the LCD.
(*) If you are using longer cables, then you can use the coupГ© bottom plate, but make sure to use M2.5x25 screws then.
