The xR4c, while a good machine, is lost between it's value cousin and the premium xR6.
The xR4 series elliptical are really not worth the money. It makes more sense to purchase the xR3 series or step up and purchase the xR6 series which are truly exceptional machines.</p> The Octane xR4 c is a good elliptical, but at $2,699 it doesn't make a lot of sense to purchase it. It isn't quite as affordable as the xR3 series, and it doesn't have the quality of the xR6 series. If you're looking at this machine, either step up or step down in this lineup, depending on what makes the most sense for you financially.</p> Ergonomically speaking, this machine isn't bad. Most of the ellipticals in this price range are similar in this area. You can, however, find several models selling for $1,000 less than this one that offer a more natural range of motion. The adjustability is a bit lacking. 15 seat height positions and 5 seat tilt positions give you several options to fit this machine to your personal body type. There are also 20 levels of resistance that allow you to make this model work with your fitness levels. Many of the ellipticals that cost less than $1,000 offer more options for adjustments.</p> As far as projected reliability is concerned, this model is decent, but if you know where to look, you can find ellipticals selling for less than $2,000 that have a longer life expectancy. The quality of parts used is nice, but it's not particularly impressive considering the high cost.</p> The noise levels of the machine are average. This is common for most ellipticals regardless of price. If quietness during operation is a major concern for you, you can certainly find better options in this price range, but we don't expect the average user to be bothered by the amount of noise this model makes.</p> The warranty on the Octane xR4 c isn't great. Labor is covered for 1 year, parts are covered for 3 years, and lifetime on the frame. You can find warranties that are significantly better than this one on much cheaper ellipticals.</p>
