Easy to assemble, great to use I'm 5 feet tall, 65 and female but put my step trainer together easily and quickly by myself! I broke both my ankles and one fibular a year ago and needed a smooth exerciser to strengthen my ankles and for cardio exercise. The stepper is just the thing and shows all the details you need throughout your workout. I highly recommend this exerciser

Contact CS for a basic question Contact CS for a basic question. CS tells me to send proof of purchase and bike serial nmbr. It has no serial nmbr. I wish I would have purchased elsewhere. Their assembly instructns are not complete. If you have not built one before this can cause severe damage. Can cause damage that may not be noticeable immediately. Those who do talk there try to blame problem on it being Chinese made. They are not nice or helpful people. Also beware of spiders coming out of box. Their CS answering system is only a run around of wasting time.

Lauren was excellent Lauren was excellent. She was very patient with me. The rower I got (sf-rw5515) is functional and cheap, which means its a good "starter machine" to see if you have the dedication and willpower to take up rowing. If you like rowing and can use this machine routinely for awhile, you can always upgrade for a better model later. The only flaw with the machine is that it doesnt count distance. It counts time, strokes, estimated calories burned, and total strokes over the machines life. But for like 200 dollars, its fine.

Follow up to December review - they're still rotten. This is a follow-up to my December review. They finally contacted me in mid January, 2 full months after I sent a video/audio highlighting the bike issue. They said they would be sending out replacement parts within 1-4 weeks, and would notify me when the parts shipped. It is now early April...nothing. How does a company that has absolutely NO customer service stay in business??? I guess they must sell enough to unsuspecting people (like me). Like lambs to the slaughter.

Bad product, worse support Blown away by this company's low quality treadmill and lackluster customer service. The treadmill I bought stopped running and while in communication with Sunny I learned that the issue actually originated from it being misaligned from the get go. The customer service tech had me jumping through all sorts of hoops to "fix" it, none of which addressed the issue at all, and in the end completely failed to stand by their product. Sunny's bottom line was basically the corporate version of "sucks to be you, maybe the retailer will care." Outside of a shady used car lotz I've never seen anything like it.
