HIGHLY IMPRESSED, snaps on tight and I have no problem with the quality.I put mine on rechargeables and forget it.. Remember they come from Chinaand you will forget you ordered them before they arrive. Bubble package in the mail.

Should come in handy. Nice idea.

Flimsy, but hey, they work fine.

Very happy I ordered these. I only use aa or aaa batteries to keep it simple. Now I will always have back up for my aa even when I'm out. Tested them and they work great. I know they are not the most powerful batteries out there....but they are the most prolific. High intensity batteries don't help if you can't READILY find replacements.

Exactly what I was looking for. I used to buy both AA and AAA alkaline batteries, not knowing exactly how many of each I need, and because some were bought so long ago that they started to leak. With these adapters, I only need to get one kind of battery. And in a situation where I need to barrow a battery or two from one device to put in another, I don't have to worry about the size anymore.

They work fine.

It's nice, very nice, to be able to buy one battery size to fit all my batter power needs. It's nice to go to the battery drawer and know that whatever battery I need (AAA, AA, C or D) that I can use the adapter holders to fit my appliances.
