🌬️ 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 Review

This is one of the cool toys for exploring POV applications. It is designed and built to quality standards. It is very easy to program; I even copied the app to a flash drive and it works on my laptop that doesn't have a CD drive. I know what it takes to build this toy and I don't expect it to last long, but this programmable USB LED RGB fan exceeded my expectations. Excellent work!

Installation, programming and use couldn't be easier! Simply insert the CD into your computer's drive (yes, it will fit. All drives have a small minidisk partition), copy the folder to your hard drive, open the folder, click on the icon, the program will open. The instructions are a bit difficult to follow at first. Find the page numbers and start with #1. Apparently printed on flat paper and folded so that page 1 appears to be on the back. One of my cheapest yet best buys from Revain!

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.

I read so many reviews and actually bought a separate fan as a replacement (I was afraid it wouldn't work). I also have to tell you that I don't usually write reviews, but I felt I had to for this item. (Photos are attached to my hand for size reference.) *** It's MUCH BETTER than I expected! *** Maybe people are very picky about the noise level or other things, but I can tell you that I work in a quiet office (cabin) and it doesn't bother anyone. - The noise is no louder than someone walking…

I bought one that showed a dial at a gift shop on a recent trip to Canada and it caught my attention at work. Of course, it also works as a decent "airflow" that forces the still air in my workspace to move when it gets stuffy. I was on Revain looking for a device and noticed this programmable one and thought twice about getting it. The reason I held back is because of the negative reviews, it broke after some use (I hope not) and it's not recognized by the PC, so isn't programmable. It came in

Well this product is what it is. This is an inexpensive little fan with LED blades that can be programmed to display a short message. It's small, it doesn't generate enough airflow to stop cigarette smoke from 2 feet away. You can feel the air as long as the fan is a few feet away, but if you're feeling overheated, it won't cool you down. Use software that programs the message displayed by the fan. I remember when CDs first came out they were rave right? But this technology is now obsolete and…
