Remember you are buying Ni-MH batteries, they are 1.2V instead of the new Lithium 1.5V that last 6X longer than this ones.
The plastic cover some time came off very easily if you are not careful when removing for charging.
The charger is very good!
If you have to stay on Ni-MH they are not bad, but if you can upgrade to Lithium you will find a huge difference.
