Question: Title: battery issues Review: One of the two batteries stopped accepting charges within six months of purchase. I'd probably used that battery 8-10 times for 10 or 15 minutes. I never got around to looking up where/when I'd purchased it, and now it's too late. Otherwise I love the drill, but it's a bit of a hassle to operate efficiently with just one battery.

Question: Title: Handy insights Review: Pamela Danziger knows her stuff and provides SME retailers (online and bricks-and-mortar) with clever insights and demographical trends on why people buy what they don't need.My products fall into affordable luxuries so it was interesting to read what she had to say.There are a wide range of products which fall in discretionary so there are some sections you can just ignore but it's excellent food for thought.I've already lent it to a friend who sells items in the hobbies category!As the book was written in 2004, the statistics don't go past 2003 which of course means some of it is already out of date as new technology has been created and adopted but overall, a great addition to your business book library!
