1 year warranty and dies after 8 months. Panasoniv offered me 15% discount off a new shaver from their site - which is 20% more than this site. Remington has 6 years warranty. I guess both brand know the reliability of their products.
I have owned this shaver for a couple of years. It is OK but not really any better than much cheaper shavers. To get a really smooth shave takes about 12 to 14 minutes and the foil and cutter need replacing three times a year.
I have owned this shaver for 5 years. It is very good but, as others have said, its performance drops and even with lubrication you need to change the foil and cutters regularly. I change every 18 months. One point - the perspex head guard gradually slackens its grip; replacements give no improvement. Very annoying. However I have found a solution. Carefully heat each end in turn with a hot-air gun and squeeze inwards by 1 - 2mm. Allow to cool and the guard then clicks firmly into place. It's then as good as new!!
