Nano bluetooth and wifi dongles work straight out of the packet - look great and nano size fits the pi zero size perfect. I also added the usb Hat which is the same size as the pi zero and sits via pins and plastic so no skills or soldering required and again works great adding 4 more USB ports and Ethernet point with leds for power (blue) and white for power to usb's all in all a brilliant piece of kit and great service from pi hut.
