Gave this as a gift. It was well received.
The assembly instructions are both incomplete and inaccurate. In fact, if you follow them EXACTLY, you'll end up putting two structural pieces together in such a fashion as to completely sever the main electrical connection between the various parts of the machine. That electrical junction MUST be made and "fished" through the pieces before the structural pieces are joined. Happily, I'm proficient with a soldering iron and was able to repair the connection by soldering the severed wires together. The "snap" connectors provided for the main wires provide, at best, a weak connection.
I stopped following the instructions at that point.
The structural cable connection between the tension setting dial and the rotating assembly is likely to confuse many. It is connected just like an old motorcycle clutch cable or a bicycle disk brake cable. The end piece of one cable must be slipped through the twisted steel "wires" of the other such that it is trapped in the mechanism.
The elliptical can be easily rolled around on hardwood floors but trying to move it on carpet is a challenge.
In use, the one improvement I'd like to have seen incorporated into the design is a longer stride length. As designed, the stride is about a "half step" for most adults, only around twelve inches.
I sincerely doubt that a small, lightweight individual would be able to unpack or move the box in which it was delivered or assemble the device. Use decent mechanic's tools to assemble it - the tools provided are woefully marginal for the task.
Given those caveats, the device works as described and is strongly built - it's a decent value for the small sum of money it costs. It is in daily use in my home, without anything breaking thus far.
