What I like on this truck:
- Looks scale, including mirrors, headlights, movable doors, interior
- It really has three perfectly working differentials
- Very grippy, soft off road tires
- All gears are covered
- Strong metal frame, just as in a real truck
- Good suspension articulation
- Proper self tapping screws are used for plastic parts
- Spare parts are available here: https://www.rcmoment.com/search/q60.html
- Identical main dimensions allow to use WPL parts, including metal upgrade parts. They are available from many sources.

What not:
- Fragile looking prop shafts, joints orientation is wrong, resulting in uneven rotation speed.
- Speed limit switching button does not appear to be working. Wheel RPM is about 600 RPM in both modes
- No proportional control of throttle and steering
- Not enough torque for rough terrain
