this elliptical is very smooth and sturdy. a lot of them i tried were kind of wobbly. the stride is perfect to where you can extend your arms and legs to a comfortable level. i would recommend this product.
Once it’s put together it seems very sturdy. But took 2 people 3 hours to put together. Almost everything is put together with an allen wrench, I recommend buying a nice Allen wrench with a handle to get some leverage as some of these pieces are very hard to screw in all the way.
I recommend 1) nicer Allen wrench, 2) exacto knife to get it out of the box and make sure you have an adjustable wrench or you may never get the pedals attached firmly enough which causes them to wobble.
I just stepped off of it and it was great, so if you can handle the assembly it’s a good product. The pulse handle bars seem flimsy, but everything else seems very sturdy.
