Review on 💨 O2COOL Treva 10-Inch Portable Desktop Battery Fan - Efficient Air Circulation, 2 Speeds - Compact & Folding Design with AC Adapter by Kimberly Allen

The O2 Cool brand used to be the leader in battery powered fans, but this company has seen better days. Over the last ten years I've had about half a dozen O2 Cool fans that I use on my regular hikes. They don't last forever (nothing lasts forever), but the materials, design, and build quality were good enough that I kept buying them. NO LONGER. What used to be a solid little fan is now cheap half-way junk. I could barely run this model on fresh batteries because something in the design wouldn't let the batteries "just sit by". When I pressed the lid it worked, but as soon as I released the pressure it went away. Batteries out, back in, same problem. Closing the lid itself was also a problem, and a closer look at the 'new' locking mechanism revealed that it was very cheaply constructed. Gone are the days when this brand seemed to deliver reliable battery-powered airflow; and now I have to rank it as one of the brands to avoid. They've had a good business for a very long time, but it looks like they got selfish and greedy and started cutting corners, sacrificing quality in many areas. Such a shame.
