Diamondback 510Ef Elliptical Review
TREADMILL DOCTOR NOTE :
The Diamondback 510 is a solid elliptcial for a reasonable price.
While you can probably find better ellipticals and cheaper ones as well, the 510Ef gives you a very reasonable combination of both. A solid drive system and a solid fram design give a relatively smooth feel to the machine during operation. The lack of stride adjustability is a drawback.
