Honestly wasn't expecting much at this price, but the MK7 Pro frame looks really clean. The welds are smooth, not all lumpy like some cheap alloy frames. Paint job is solid too — no weird bubbles or thin spots. The internal cable ports sit flush, and the UDH hanger bolted on without any fuss. Feels like a frame that costs way more. Pretty impressed for $259.
