Review on Vornado EXPAND4: Compact Air Circulator Travel Fan with Collapsible Body - Powerful Multi-Directional Airflow, Built-in Carry Handle, Cord Storage - Black by Kelly Jones

As always, the build quality of this fan is excellent. I have (3) other Vornado fans; 1 personal Zippi fan and 2 VFan Mini Classic vintage fans in green and vintage white. Extension 6 has less air volume than the other two fans. In fact, Zippi's personal fan is very compact and folds up easily. What's really annoying about the Expand 6 is that IT WON'T STAY IN THE POSITION YOU SET IT IN, meaning it will always lean towards the ceiling if left alone. The fan must be mounted on a door or similar to prevent it from tipping up. In my opinion, the Zippi fan is better suited for travel.
