Pros: Works great. Will take AAA and AA batteries, 4 total at one time. They charge in sets of two. Charging takes a little while but it's okay - use a couple packs of batteries to swap out and re-charge. The biggest use is for my kid's LeapPad, which eats AAs in sets of 4, and this charger keeps up great.

Cons: No complaints.

Pros: - Keeps your Double AAs charged all the time.
- Charges quickly.
- Battery lasts pretty long when fully charged.
- I use two of the batteries for a Logitech remote, which burns through batteries and was costing a good amount of money, but having four batteries on rotation, the remote is always charged up and ready to go.
- Sits on the wall and doesn't take up too much space, and is rather inconspicuous.
- Has a green light that will indicate the batteries status.
- There are 4 additional slots for triple As, though you'll have to purchase them separately as only AAs are included.
- Saves money if you use a lot of batteries.

Cons: None really. We'll see how long the batteries last without failing.

Other Thoughts: This battery charger is just all around great, and I've heard Eneloop is the best in the business; I have yet to believe otherwise.

Pros: It charged the batteries for my graphing calculator.

Cons: None.

Other Thoughts: Only used it once so far. It charged my batteries just fine. No reason to believe it will stop working. It has two different positions, one for AA and one for AAA, and it seems to charge the batteries in two separate banks. The LED flashes when it is charging and stays lit when it is done.

Pros: The batteries are really really good qualities.

Cons: The charger is not really good. It can only charge 2 or charge 4 batteries at once. i.e. charge in pairs (this is not ideal) You can make those great batteries run even longer/better if your charger can refill the juice individually.

So for serious users who want make the most out of the great 4 batteries included, please buy your own charger. :)

Other Thoughts: .

Pros: Comes with 4 1900 mAh batteries. The packaging states that they can be recharged up to 1500 times, outlasting most other brands by a large margin. I haven't gotten anywhere that number yet, so we'll see. ;)

Cons: None so far.

Other Thoughts: This is the same battery that came with my Logitech G700 mouse. Sounds like a solid endorsement to me.

Pros: Excellent battery life, easy to use,

Cons: None so far

Other Thoughts: While looking for some strong rechargeable batteries for my Pentax K-x DSLR I came across numerous reviews touting the greatness of the Sanyo Eneloop battery, naming it far superior over every other rechargeable and even over most of the one-time-use AAs, so I picked up a few hoping to save some money in the long run and so far, so good. Most AA single-use batteries tend to start showing a power drain around 30-50 shots, but the Sanyo are still going strong after this point. Hoping that these things live up to their rep., but so far everything seems to be as represented in the bajillion reviews elsewhere on the web!

Pros: Very pleased with these rechargables. Last nearly as long as certain "name-brand" (see overpriced) NON-rechargable batteries on a single charge. Charge up from completely dead very quickly (within a few hours). Hold an excellent charge on the shelf for a loooong time...I've used those other "name-brand" rechargables and if you don't use them within a week of charging them they'll be dead...I charged my Eneloop's and didn't use them for nearly 2 months....still had nearly 100% life! These take as many pictures in my camera as NON-rechargable batteries do, and I can use them again and again. Gonna buy a second set (AAA), and for my needs, that should last me for a looong time as far as batteries go. No more paying $12 for a package of batteries that have to be thrown out after they're used, and no more paying $20 for other branded rechargables that last half as long and don't hold a charge on the shelf. I found my brand!

Cons: None, couldn't be happier

Other Thoughts: I've tried a lot of different brands before finding these...they truely are better.
