I bought Philips QG 3387 Multi grooming kit 4 months ago and touch wood, I have been very happy with the product. I have contemplated a lot before I bought this product. I bought his particular model because of the 8 different adjustments it comes with, which takes care of the whole body.
Also, Philips is a very reputed company and I have been using their different products from my childhood and it has always been dependable. I also bought this product because I dont like to shave everyday and as a result of that the beard gets very soft and a razor would be ineffective.
I also thought of buying Panasonic and Remington but Panasonic was too expensive and Remington I didnt like. If you hate to go to a salon and like to style your beard differently, then you might want to consider this one. I is a powerful machine and gives you a perfect trim.
The battery takes one hour to charge and I have used of continuously for 20- 25 minutes. I havent complete battery drain time, the company claims it to be 50 minutes. And the best thing about the Philips trimmer is, it is completely waterproof.
