Review on 🌀 Optimized Vornado 610DC Energy Smart Medium Air Circulator Fan with Adjustable Speed Control by Teri Washington

What happened to the quality of Vornado? This is my second return of a defective Vornado 610DC Energy Smart Medium Power Air Circulation Fan. The connection between DC and AC on the first fan was very weak. Even something like the wooden floor vibrating from a wheelchair moving nearby was enough to knock out two power supplies. The replacement is slightly better. However, it wasn't securely connected either. The fan had a constant pause in current flow for minutes at high speed. This uneven on/off noise when humming is annoying, among other things. The Vornado 530 compact all-room circulating fan I bought in 2015 lasted eight months before it died. I didn't have time to report it and ended up throwing it away. The same fan 530 purchased in 2008 still works as I expected from Vornado. I tested the 530 fan at maximum speed. There's no erratic fan volume and silence from 2008, just a steady, steady hum. Do I want to try a third Vornado 610DC and hope the third time will be nice, that this time I get a fully functional fan?
