question:
I have had the charger for more than two years. It charges AA batteries just fine, but has a huge problem securing smaller AAA batteries. To charge the smaller batteries you need to flip down the little button at the positive end. In the beginning one of the four AAA batteries would pop up, and now three out of the four won't hold. The problem is the flip mechanism became loose, and any horizontal pressure would push the buttons back up. What I have to do now is using duct tape and a segment of crayon, apply the crayon on the buttons, and wrap the tape around. You know how painful that is.
answer:
Negative

question:
Standard Michael Bay garbage. Totally removed from the original idea, especially concerning Optimus Prime's character. The ideals the character originally stood for are completely ignored in favor of kill shots and 'Murican tough guy crap.
answer:
Negative

question:
This product looked fun but in reality was very uncomfortable and it vibes only at the middle! It's also very large (long) and didn't fit very well! Anyway, in summary, a neat idea, but not a staple or even fun for a one time use!
answer:
Negative
