Review on 🌬️ 8in Portable Desk Fan with Real Time Clock and Temperature Display - SAYTAY 7200mAh USB Rechargeable Battery Operated Foldaway Table Fan, Adjustable Height, 4 Speeds - Ideal for Bedroom Office Outdoor Use by Jared Surabhi

My first impression: The build quality is much better than expected. Text display: IMHO super bright. Resolution/Graphics: Surprisingly good. Built-in demo: a pleasant surprise. Cons: Vibrates a bit (doesn't matter), the blades are such that there is almost no air blowing (another minor point since I was only interested in the POV effects). Overall I can't believe how cheap this POV device is. I recommend you to buy it as a POV (Persistence Of View) demo, not as a "permanent" fan.
