Bought this for my wireless mouse. The performance is quite good so far. The battery does hold the charge for about a week after daily usage of about 5 - 7 hrs .

Good product .. Working very will with my nikon cool pix L810... A good buy... Also battery lasts longer

These batteries are thicker than normal AA batteries & were difficult to fit into my Canon 430EX II Flash.

My flash's battery compartment accomodates normal AA batteries very smoothly but, it was tough fitting these in & once they were in (with effort), they were impossible to extract.

I had to take my flash to a Canon service centre to have the batteries extracted.
Can't use these again.

They may work with a device which doesn't adhere to standard AA battery sizes but definately not w...

good quality.must buy

I brought a monster truck from Germany, somehow it is not working so I again imported the batteries from Germany ..I am not sure what's wrong..

I am reviewing this product after about 70 - 100 recharge cycles of the Envie 2800 mAh batteries.
The pros are - they look like every other rechargeable battery on the internet.
The cons -
1. Too Expensive. Over priced.
2. They do not have an official website which lists this product. They do have a website which is managed and run by the company that ships these products to India from China. Yes, this is a product made in china with a sticker slapped in India. I don't mind using products...

I used the product in my camera only on 1 occasion and then after when I used battery next month was not even able to click 20 pics. I started getting message low battery when I replaced it with the other 2 battery got the same message with in 20 clicks.
My Kodak battery and the other 2 battery which came free with camera more then 4 years old still helped me to click little more pics then this new batteries.

I have bought them from a local vendor, came to know about this brand then only.
I am using them on my Yongnuo 560-iii manual flash, for coveirng weddings( not on full flash power, but ~ half almost all time), they last easily upto 250-400 shots. Never shot more than that in a day with flash, I m sure they will have juice for another 50-100 shots.
Overall a great product to use on external flashes. :)

I took full liberty with this. After one full charge I used this to take approx 400 to 500 photos with my camera, and that too with intermittent videos.

It's a great buy...

Good
