Exactly what I was after. Other vendors were not so comprehensive regarding the shaver models that the item was applicable to, but shaver-spares.co.uk were right on the button, eliminating any doubt. The price was competitive and the delivery time was excellent. All in all, faultless.
heads are half the price of the original Philips Heads but not quite so good a shave. However the originals are no longer avaialbel so thank you for sourcing them
