Bought it a month ago, almost used every 2nd day, here's the review.
Backup and Charging:
1) Charging Time: 8-10hrs, may increase with time with normal wear and tear as with every product.
a) Runs for 30-35 Minutes, even more, on a single charge, One charge is basically enough for 10days!
2) Trimming, Styling hardly takes 2-3minutes, So one charge is more than sufficient for your needs, Hence, battery backup should not be an issue, charge once a week, and it will go fine for years.
3) All those saying it isn't corded, It's for your own good, Imagine the risk of getting an electric shock while trimming your beard, You won't want that, Right? And you will also not run it for whole 35-40 minutes at one go. Maximum 5 minutes is what you'll run it, hence, backup is more then Enough.
Performance:
1) Product performs flawless, cuts hairs smoothly, no matter how long your beard has grown. I've been using Philips Shaver too, and even after 3 years, it runs as good a it was for 1st day. Although, used moderately. So blades should not be in doubt.
2) Yes, No Oiling needed.
3) Washable blades, Easily removable and cleanable, However, I didn't find usage of washing it, a blow of air is enough to clean it.
4) Less vibrations and moderate sound. Comfortable for user.
Accessories Supplied:
Comb: Not the comb you use for your hairs! It fits with the trimmer, and adjust for various lengths, ideal for styling mustache, french cut etc. Quality is good. Handle with care though.
Brush: To clean those tiny little hairs on the device.
Charger: You can either charge or either use it, No Charging while using it, Light will glow on Charger, but it won't go out, even if it's charged.
Few Leaflets, and Yes, Register it on Philips to get an extra year of warranty. The backside of trimmer will have a 4 digit number, above model number, that's your serial number, still having issues? Call Customer Care.
Overall Review: product's great! Amazon's price is comparatively cheaper with all, flipkart too, delivery was within 2 days, without any additional delivery scheme asked for. Delivery Guy was very professional, and packaging was rock solid!
Go for it, it's more than enough for all your trimming needs.
