Only website that had a full list of shavers, (mine was an old model) so I was sure of getting the right replacement cutters. Order arrived the following day . Very competitive price.
Where to obtain shaver spares locally is not always an easy question to answer. I found ShaverSpares from an on-line search and placed my order using their parts identification process. The parts arrived next day by 1st Class post. Excellent service in my view.
