Is the DeerRun Z10 worth it over a flat walking pad?

If you want incline, yes. The 12% auto incline is rare on pads in this class and lets you raise effort without changing speed. If you only want flat walking, a flat pad does the same job with fewer parts.

How fast and how steep can it go?

Speed runs from 0.6 to 3.8 mph, and the incline adjusts automatically across 12 levels up to 12%. Both are set from the remote or the PitPat app.

Does it fit under a standing desk?

It is 6.2 inches tall and 43.76 inches long, so it slides under most standing desks. Check your desk's height range, since the deck height adds to your standing height.

Is it good for tall users?

Be careful. The deck is about 43.8 inches long, and some owners say it feels short. Taller users with a long stride may find it cramped at the top speed.

What comes in the box?

The walking pad, a 5.9 ft power cord, a remote control, a silicone oil bottle and a hex wrench. No assembly is needed.

Does it need assembly or lubrication?

No assembly: it is ready to use out of the box. A silicone oil bottle is included for belt lubrication, though some owners say the belt still squeaks after oiling.
