Mini micros are fabulous. They are so good. Both my boys learned to ride at about age 2. Having the 2 wheels at the front makes a huge difference than two at the back - they don't get in the way of their foot/leg as they scoot. Ours has had thrashing and it's still going strong. You can get replacement parts, but we have not needed to yet.

Learning to lean in order to turn is a great skill. So much safer than turning a handle.

We do a bit of off road scooting, but it would be hard to learn that way.
