This is a very nice desk. The Bamboo desk top was thinner than I expected, but it is stable and sturdy (even after screwing some hardware into the underside).
I should have bought one of these 10 years ago. My back and my legs feel much more pain-free and strong. Also, I am much more productive. If you work at a desk, then invest in yourself. Buy one of these.
The E7 is perfect for me. Assembly wasn&t bad at all took around an hour, and it is indeed heavy as others have said so you will probably need help moving it around especially after it is all built. I saved my sit and stand settings and everything works great. The motor isn&t loud at all and moves at a decent speed. I definitely recommend it.
