Unit functions ok for the price point, but the battery failed (would not hold any charge) within an unacceptably short period (within the guarantee period, but Philips only offered a 15% discount off buying another from their website - which is still more expensive than other retailers and not an appropriate solution). This also happened with another Philips shaver. As with all 4 Philips products (including a high-end Sonicare toothbrush) I've purchased, all have failed and Philips have never satisfactorily resolved the issues (only ever offering minor discounts from their shop, not in accordance with my statutory rights). Accordingly, I won't be buying any Philips products again.
I was amazed at how quickly I received my Clippers, considering the lockdown at the moment and with people working remotely etc due to Covid 19. Cheers Gerry G
5450 Clipper worked Ok for 18 months, but then the plastic variable-length clipping-comb failed (in an unnecessarily mechanically weak area). Philips refused to replace the clipping-comb under warranty on the grounds that it was an "accessory", despite the break rendering the variable-length function unusable. The replacement part is £7 (including p&p), so factor this into the initial purchase price. The clipping performance is fair (4/5), but not great on fine hair, and my old Wahl clippers with an angled fixed-length comb did a better job around ears.
