The M7 Pro follows the same design language as previous Nighthawk routers, a compact, square unit with rounded corners, finished in a dark matte plastic that looks appropriately business-like without drawing attention. At 105 x 105 x 20mm and 275g, it is pocketable in a jacket or bag side pocket, but just slightly too large for a trouser pocket. For context, it is 75g heavier than an iPhone 15 Pro, which gives a reasonable sense of what you are carrying.
Build quality feels solid throughout, with a reassuring weight that suggests durability. The battery and SIM slot are accessed by removing the rear cover, a slight press and pull on the corner tab reveals both. It takes a little confidence the first time, and the battery can pop free if you are not careful, but once you have done it once, it is straightforward. The USB-C port on the base handles both charging and data transfer, and on each side, there are two small slide-down covers concealing the optional external 5G antenna connectors — a useful addition for low-signal environments, though the antennas cost an additional £45 and are not included.

The 2.8-inch colour touchscreen on the front is genuinely useful in the field. It displays data usage, connected devices, network status, and Wi-Fi credentials at a glance. I found the option to display the Wi-Fi name and password on screen helpful when quickly connecting colleagues on a shoot. When working in public spaces, I switched it off for obvious reasons.
