When choosing this brand, we turn to a product that has a solid reputation. I use these batteries in a game with the wind tunnel and I could see the difference with the first battery price that I had chosen first. So, I renew with this pack because I am confident next time. By cons, given the price, they are to be used for a product that is often used because it would be a shame to lose their effectiveness over time (my son often forget to fully extend the games, so I watch!)
