Pibow Zero W
The Pibow is very compact, wonderfully colourful, and easy to assemble - although I did find assurance through following the guide on the Pimoroni web site. When inserting the bolts, I did have the shim layer slip out of position, but that was obvious and easy to remedy. I was a little surprised to find that the microSD card cannot be swapped with the Zero in place. This is of little importance to me, but it may be worth highlighting to some buyers.
