I'm pretty pleased with this purchase. It functions just as I had hoped for. The length adjuster is useful, and allows you to choose between the shortest setting- 1.5mm (although I think it's actually a little shorter than that- perhaps 1mm) for that designer stubble look, through 8 stages up to 18mm (should you like your beard a bit longer). You can also remove the 'comb attachment' to easily trim sideburns and edges with the cutting-blade itself, which gives a safe (nick-free!), close cutting action. It's quite easy to use, with a simple flick of a switch for on/off settings, and a neat locking, rotating switch to select the length. The overall shape is ergonomic,and as you would expect, it fits quite snugly into the palm of my hand. It's tough plastic too- I've dropped it a few times, and it hasn't broken yet! It's also cordless and rechargeable. A 10 hour charging gives me around 40 minutes worth of trimming time (although this decreases with the age of the product). I use it for about 5 minutes at a time, so it usually gives me approximately 7 or 8 sessions between charges. Cleaning is only occasional (as most of the longer hairs can usually be blown or brushed off without it- although the brush that comes with the trimmer is a little puny to say the least, so you're better off finding another one), but when cleaning is required, it's pretty easy to do, thanks to the hinged cutting unit that swings open with a little tug, allowing you to quickly dispose of any bits of hair that may have managed to get inside. Overall, a pretty good purchase, that I would recommend to all stubbled/bearded folk!
