Title: A good battery fan but not compatible with all batteries
Review: I have had 3 O2 Cool fans for a numbrer of years. I use them at dog agility trials when the weather is hot. I run them at low speed and the alkaline batteries last for several weekends. Recently however, the D batteries I have been buying don't fit properly in the battery compartment!! The bumps on the plus end of the battery are too short to reach across the partitions that stabilize the batteries in the holders. The bumps on the Walgreens batteries I buy have been reduced from 0.115" to .075". The old ones work and the new ones don't. The Energizer alkaline batteries I have on hand don't work either. If you want to use this fan, first determine where you will get the batteries for it.
