I am very pleasantly surprised by this. I nétais not at all heavy and bulky rechargeable battery charger and battery life by extraordinary value for money was not good for me. Having a child of my 3 year battery consumption has more than doubled.
the charger is compact and lightweight. but especially in 4h AA or AAA batteries are recharging. they have a good battery life and for the moment I do not see piles of speed loss.
a good product that made me change the look I put 4 stars because I did not have enough to get back the real life of the batteries in 6 months
