Very stable, solid construction. If you carefully read all joint parts a bit with bearing grease once enough built in peace within 90 .... 120min. The computer is rather prehistoric and is somewhat reminiscent of a bygone era, but the mechanism in Taiwan is automatically generated and powder-coated, really very solid. A rubber mallet for assembling the way you need only when close tolerances, precision crafted to fit, with no moving parts lubrication (and mindless), to be joined by force. The stowage of the cable harness in the head part of the device could be better thought out, but I will not complain about the vast number of successful artisanal details of this entire structure. Important at our discretion, it would be for other interested parties, to go up a heart rate monitor from the outset in connection with this device. Unfortunately, the information distributor side this bit poor. Our tip: From the distributor of the Polar chest strap is the heart rate sensor favourisiert with radio transmission to the computer of the device. This works perfectly, but does not have a display (only on the Maxxus computer). A Sigma Sport PC 15.11 heart rate monitor, in which is a chest here is, from Maxxus cx6.1. exactly identified. The Sigma pulse computer shows on the wrist, the heart rate and can therefore also be used on other devices or while jogging. The real reason for the indication of the heart rate monitor: An elliptical machine as this brings the normal really trained people with a successful, smooth motion already "half power" after 30min very in's sweating. In order for this stress is also healthy for us and we are not overwhelmed (you will notice this is not the same ...), the pulse should be mandatory controls - finally heck yes fun and not be the last thing you're doing so ... Clear recommendation, the thing is worth every penny.
