The fan itself might be really great. I wouldn't know however cause I couldn't get it open to insert batteries!!

Not real surn but my son used it a good bit for summer camp and it was hot !! 7 days straight and the batteries still work.

I don't leave them on all the time but at least 20 to 30 hrs prob more. They are a common size flat battery easy to replace and has like 3 settings of flashing and one solid. My batteries havent ran out yet.

I bought them a couple of months ago. I don't see a date anywhere on them but there is a stamped number of "43" on the battery. All the batteries were fully charged and I did not have any defective ones. I have bought the same batteries before from these people with no regrets.

Batteries will last 20 to 40 hours depending on factors such as quality of batteries and if headphones are being used to save power.

On a fresh set of 2-AAA alkaline batteries, I managed to get close to 50 hours of listening time, over the course of about 2 months. Completely blew me away. Before that, I tried a set of the more-expensive Energizer Lithium batteries, and I only got about 25 hours out of them.

Site says 60 days warranty. If you don't use all the batteries by then, you cannot complain or try to return them. There is not a date on any of the packages I have received. It has been over 60 days since I got my batteries, but they don't last long even when "new." You get what you pay for. If you need quality, you have to pay for it. My dog loves these batteries in his training collar.

I think the product description needs to be changed. Typo. Batteries last 7-9 days and shelf life is over 1 year.1 pack of 60 is my years supply.

The expected life span of these batteries is approx. 1 year give or take a few months. My last set lasted 2 years

I have used my set for nearly a year with no problems. The batteries should last at least a couple of years if not 3 or 4+.

I do not know the exact time in hours and minutes, but my has lasted forever. I'm in and out of my gun safe alot, I leave mine on motion setting and have yet to pit new batteries in it. A+++

Can't give exact time but they last pretty good time. They use reg AAA batterys.

Like the others said I guess it's in the item specs. To be honest I've never had to replace them or anything. I have two of these and one has been going for a few years. Admittedly they only get used on occasion but the batteries have held up.

I think it also depends on how tight is the fit between bolt and door. If the motor has to push hard, batteries will drain quickly. My first set lasted about four months. Second one is about three weeks into it and shows 100%.

I have had mine for 10 months now and my husband tested the batteries a couple of weeks ago. They still tested pretty strong so my guess would be something in excess of 18 months.

Best I can recall, NO. But this should not even be an issue since one battery will probably last about 10 to 15 years.

I cannot really confirm the 3 hours number: I can tell you I have only used 1 set of batteries in 3 months of fairly regular use. I rarely have the light on constantly for over a minute at a time though. I bought my batteries online at Home Depot-surprisingly good price and name brand. Am happy with the light so far--extremely bright-good range.

The Power One batteries, in my opinion, are the best on the market and provide the best performance for my hearing aids. I can count on them lasting 7 days and I use them about 16 hours per day.
