I've read all of the Night World books, and this is a great book, but I must say, it's not L. J. Smith's best
Positive

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.
Negative

I am now on my second Pioneer DVR 633HS.It's got to be the biggest piece of junk I have ever owned. They last about 2 months(or less), after that they do not respond to any controls and keep turning on and off on their own. My first one got so hot it could have set the house on fire had I not caught it. The hard drive locks up and keeps sounding like an old pulse tone telephone.Did Pioneer get rid of all educated engineers?I noticed this unit cannot even be purchased on -line at any web site anymore. This is sad after only a few months on the market. I will unload this piece of junk back to the dealer and buy any other brand but another Pioneer.
