[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]: Personaly this is one of my favorite books. It's one of those books you can read and re-read again and agiain, without getting sick of it. The way Farris is writtin and the way Alanna portrays him is awsome. Then the differennce you see from Farris-to-Bantam is wonderful. If you like reading books that don't hold back and make the characters seem above everything, but sound realistic but also adds magic in with that then, this is a book for you. This also isn't one of those constant blood-bath books or romance all the time books or the main "character gets the girl everything turns out in the end" books. It also doesn't have a tragic end were you begin to wish you'd never wasted your time on it. No when you finish reading this book you will NOT regret reading it. I've said to much. Oh, well. Read it and see for yourself if you agree with me!!!
[EX A]: Positive

[EX Q]: The tray was thin and cheap looking and although it was supposed to have rocks included, there were none in the box. The only part of it that was half-way decent was the rakes. Because I was on a time constraint I kept it, but I did have to go buy rocks and I also bought more sand because what came with it looked like salt.
