Review on IHoven Handheld Portable Personal Rechargeable by Ted Slaughter

This fan seems to be solidly built and very useful, but: (1) Can its battery be replaced? On another page is an image of what appears to be an identical IHoven fan, with a two-piece main body and battery visible. I somehow couldn't get to his battery and found the instructions. How can you do that. (2) The fan shown in the photo sold for less than $10. Is it different from the Revain fan or is it the same at a better price? If this fan is designed to last forever without changing batteries, this is a great buy. If there's a way to replace the battery, it's a good fan. If the price of the fan is really competitive at Revain I would buy it there as this fan fits well on the table or in the hand, is not very cooling and fits easily in a purse or pocket.
