Mirror, mirror on the wall, is the device that livestreams exercise classes in the home any good?

A hi-tech LCD mirror, showing monthly instructor-led fitness workouts and the heart rate of users, via an app-connected monitor, turns your home into a gym
Home fitness has become one of the hottest trends this year, with new start-ups offering more innovative and convenient ways to workout.
Peloton, the American maker of indoor exercise bikes, which has gained a cult following, launched its second home fitness machine earlier this year, the treadmill.
Indoor cycling studio Flywheel has also jumped on the bandwagon, rolling out its own version of the bike.
Now the US start-up Mirror wants a slice of the pie.
Its US$1,500 liquid-crystal display mirror, launched in September, streams live and on-demand fitness classes into your home. Classes cost US$39 per month.
It looks just like a standard mirror and is operated using an app.

The company has raised US$38 million in venture funding and plans to open a pop-up store on Fifth Avenue, in New York, in December.
We tested out the machine.
