Philips have been always been trustworthy brand when it comes to the accessories. so keeping that in mind I purchased this trimmer and they don't let you down with your expectations. here are some simple points why you should go for this one.
1.portability- you can use this trimmer without getting wired to yhe switchboard. come in handy for travellers( lond trips) .
adjustable jaw- there is a glory plastic head, controlled by the roller settings at the handle arm to set to want your beard get trimmed.
accurate- with 0.5 mm precise adjustment you can reach the corners of your neck and trim with ease.
no batteries / chargeable- gives you 45 min backup for continuous use, however assuming 10 min for each trim you can use it 4 times on a single charge, however, I said it gives 45 min of backup but it comes with the cost of 12 hrs of charging! but its not your smart phone that you use regularly so for a trimmer it doesn't matter much. I would give 4 stars only for this fact and its really good looking highly useful trimmer.
