Putting it together was a breeze, and the mode transitions are super smooth. It's light enough to move around easily, yet feels solid and well-built. I can tuck it right under my bed! I Just opened it up today and already loving the sleek design excited to make this part of my regular fitness routine!

I love my new Wonder Core fitness machine! Assembly was effortless, and switching between modes is intuitive. While lightweight, it's surprisingly sturdy, and stores easily under my bed (though too tall for couch clearance). Unboxing was easy %26 I'm already thrilled to have this in my home as my my go-to trainer! No more driving to the gym for me.

This is the best workout I've done !!! Very well made super easy to setup for someone with a bad back .. I'm very pleased !!!! Thank you

As others noted, the screws are much too short. The screws for the base are the worst. You can barely get two threads and that's without using the lock washers so I would say it's not very safe.
