This is the elliptical equipment that my gym has and I love it. It works out your arms as well as your legs, which is the best part - a total body workout. The programs are easy to follow and you can hook up your heart rate monitor to it to track your heart rate. Also, there is an AV plug so you can listen to the audio from the connected TV or listen to your own music. There are channel and volume controls on the monitor. Performance Good performance overall. It's easy to use and the programs are very straight forward. Comfort I'm a petite person (5'2" and 115 lbs). The machine is a little big for me but then again, lots of elliptical and training machines are. It would be nice to have adjustments to the pedals but I don't believe any elliptical machine has that due to safety reasons. Ease of Use There are pre-programmed options as well as a manual option. You can also enter your height and weight for more customized tracking of your calories. Durability The machines have been at our gym for awhile now so I assume they are durable.
