No doubt about it, this is a quality product. I've had a number of corded and cordless drills over the years, and the Lamborghini certainly has the edge in weight, power and features. It has all you would expect or need from a drill, variable speeds and torque, comes with two Lithium Ion batteries and a small set of bits (although let's face it, if you're willing to spend £160 on a drill, you'll probably want to buy a separate set of drill bits). It has a spirit level to ensure level holes and even has a (slightly mis-angled) LED to light up where you're drilling in dark corners (in fact, slightly below where you're drilling).
So, the crux of the review of the Lithium Ion version - is it worth £70 extra for the benefits - lighter, longer battery life, lack of "memory"? I've got to say, I'm doubtful - you would have to be doing a serious amount of drilling for it to be worth your while. Given that the standard battery version comes with two batteries, you would have to be running the second battery down before the first one had recharged. Also, keep in mind that for £20 more than this drill, you could buy two standard Tonino Lamborghini Combi-Drill Hammers, giving you the flexibility of two drills (one for the drill bit and one for the screwdriver head) and four batteries.
All told, I would give the drill five stars, but I've dropped a star off the overall rating on the basis of value for money. There may be some for whom the extra cost is justified, but I would have thought they'll be in the minority.
