The Advance S2 is our newest offering from the same manufacturer as the Commercial/Manual/Pro S2. It features the same high-quality metalwork however the Advance is driven by Bosch motors and features the manufacturers own electronics. The Soho S3 features 100% Chinese frame, electronics, and motors from our other manufacturing partner. Functionally it is largely the same as the Advance. Both desks also come with a digital handset controller, but the controller for the Advance also has a USB outlet for charging your phone or other accessory and has 4 memory pre-sets compared to just 3 memory pre-sets with the Soho.
