I was expecting the chassis to be quite flimsy (considering the price), so this did not alarm me when I noticed bending, and some parts not quite matching up. I was disappointed mainly with the accessibility to the on/off switch, even after making sure to purchase a very short micro usb lead. You pretty much have to take it apart each time, if you want to conserve the battery life. I also bought it for my advanced students (11-13yr olds) and they had great difficulty putting it together. Maybe it is better off for a hobbyist. Still love the Micro:bit and all it has to offer, just wishing that this was up to the same standard.
