Thought it was about time I replaced my heads after 18 months, although they still seem to cut alright. Very easy to do, and as I suspected there seemed no difference. Well at lease I will enjoy another 18months from them at least.
For an electric razor I am very impressed with the speed of shave and closeness compared to other electric razors I have used in the past. They have come a long way over the years or this firm is exceptional.
