What is the difference between this and a walking pad?

A walking pad has a motorized belt for walking at set speeds. This pad is a platform with vibration levels, meant for standing or slow movement, so it does not replace a treadmill for distance walking.

Does it track steps, speed or calories?

The listed features cover an LED display, three vibration levels and a remote. No step, speed or calorie tracking is stated, so treat it as a movement pad rather than a fitness tracker.

How much assembly does it need?

It is listed as requiring assembly. Expect to attach the parts shown in the box before first use; the remote and display are part of the unit.

Can I use it while working at a desk?

Yes. It is designed for portable under-desk use, so you can stand or walk slowly on it while working. Keep sessions short at first while you adjust to the vibration.

Is it loud enough to disturb others?

Vibration platforms hum and vibrate rather than run a belt. No noise figures are given, so judge it in a quiet room before using it in a shared office.

Runners and anyone wanting incline or speed workouts should look at a motorized treadmill or incline walking pad. This is for light movement and standing.
