Honestly I thought I would have issuses with my elliptical because of the reviews, so I waited over a month to write a review. I am SO GLAD that I got it! Im on it 6 days out of the week. My knee had problems before and it helped unjammed my legs. I'm gliding up stairs with ease and no pain. I made sure to place each nut and bolt properly to make sure that noise isn't an issue. It doesn't squeek.The only down side is the highest resistance doesn't feel that hard to me. I've dropped out of the 300s when I bought it I was 329! Get it! Assemble it correctly and USE IT!

I purchased this Elliptical machine and also The Sunny Treadmill. They are BOTH excellent machines for the price of of $500 each. It took about 45 mins to assemble the Treadmill and took us about 1 hour to assemble the Elliptical machine. Both run smoothly and quietly and we love our new workout room. I also recently ordered the Sunny Ab machine as well. I will do a review on that as well once I get to try it out. Thanks Sunny Health. Love your products

Read a lot of the reviews before I purchased this product. Gave it a shot. Product arrived with all of its parts. It took me a little under 2 hours to assemble. The instructions were easy to follow. Greatest thing is that it doesn't squeak. I work out early in the morning so I don't have to worry about waking up my family. I'll do an update in a few weeks to tell how it's doing.

Motion
I have found the motion smooth and comfortable throughout the cycle.
Resistance
Currently using the lower settings.
Display (battery powered)
It provides the basic functions but I prefer to use my Mio bluetooth watch with an Android Simple Heart Rate app display positioned at eye level.
I have not used the Sunny app.
Noise
It is very quiet, no nasty horrible noises which some machines make.
Assembly
I have assembled machines before so I found it okay to do by myself. I used a large flat trolley I made to move the large box it came in around. The box said to turn it upside down but I found it easier to cut down the sides and move it out sideways. It came with standard flat pack type tools. I used some of my own tools for a more comfortable assembly experience. I also used some B&Q Diall Corner dolly trolleys when attaching the levelling feet underneath the unit.
Price
It is reasonable for a quality machine which is comfortable to use.

Was surprised as I took the parts out of the box. Much sturdier materials than I expected and even though the carton was slightly damaged, the parts were still securely fastened to the foam holders inside. The assembly portion of the manual was reasonably easy to follow and the numbered card with the assorted fasteners and tools made things even more easy. Another surprise was that all the mounting holes lined up and the screws and bolts threaded in easily. No modifications or cursing necessary. The plastic joint covers are solid and were also easily fitted. In reading some reviews before purchasing, a common observation was that the stride is a bit short at 15.5 inches. We don't find that to be the case. Both my wife and I are in the senior category now and she is also on the short side, so it works just fine for us. The operation is smooth and quiet. Considering the quality of the machine, it would be nice though if they would include an incline adjustment option on it. Overall, if you're on the short side or a senior this is an excellent and inexpensive way to go for an elliptical trainer. One whine to make, perhaps didn't read things closely enough while shopping, but I was surprised to find Made In China on the carton. Sunny ought to do something about that.
