Opinions on cordless screwdrivers?

I want to buy a cordless screwdriver as a gift. I'm looking at the Mastercraft 3.6V Lithium Ion Screwdriver (item # 54-2740-8 at canadian tire) it seems a good value but I haven't had any recent experience with cordless screwdrivers. the last time i used one was nearly 20 years ago.

Can any one shed some light onto this and tell me if this product is good, or can you suggest an alternative?
