Product arrived very quickly after placing the order on 24 August 2014. No e-mails reached me however. Installed the cutting head and disposed the old cutting head - just to find out that the performance was far inferior to my two year old shaver head that I had just disposed. Thought it maybe was me, so cleaned it thoroughly but to no avail - now the RQ12 needs replacing, cannot take a chance (or expense) with another replacement head, but this one just does not do the job.
Shaver now works like new again.
Excelent service less than 24hrs from ordering item was delivered, can recomend..
