[EX Q]: 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.
[EX A]: Negative

[EX Q]: Received this in great time- I have no problem with the seller:-)BUT! The inside of the case lists all types of materials this can cut including metals, which is what I got it for.One punch through soft 26ga copper sheet and the edges of the punch bent & in some areas, flaked off. The second disk I cut did it in completely. I had to file all of the edges and it probably would have been easier to cut the sheet with shears.So, not for metals.However, I can see it would be great for leather, paper & plastics.To me it was worth the money spent on the chance that it would actually cut metal disks.
[EX A]: Negative

[EX Q]: I love to see the Transformers in movies but I will never get the time back that I spent watching this movie. Good actors in a crap movie do not make a good movie. Fantastic special effects do not make a good movie. A well written story and characters that you care about make a good movie.
