Well in the past I've purchased the copies of these and even some that purported to be genuine but off both eBay and Amazon, and they never gave a great shave so thought I'd buy originals from a genuine seller known seller and my lord what a difference, so much smoother in use and a closer shave, my shaver is back to like new again. Straight away even the packaging is so obviously genuine and far more robust. Ok they're 2.5 times the price of the cheap ones but worth every penny. I will be buying these in the future.

Great product very well made ,true brand ,don't buy cheap ones they are rubbish.

So they definitely worked on my razor which is much improved, a much better shave which takes less time.The downsides are that they are expensive for what they are and the fitting instructions on the packaging are really small and even with a magifier you'll struggle to understand them. Works with a S9711 shaver if you have one.

They are genuine philips replacemnets so quality and fit are perfect, although on Amazon they are cheaper than the Philips web site. These were a direct replacement for my original SH90 heads for my S9711. Easy to install and they make a huge difference when shaving. Defentley worth paying slightly more than the many copies available.

Like the original blades. Far better the cheap replacements . A nice painless shave again

Loved these. Changed my 3 year old shaver in a new 1. Fitted perfectly

Original parts all works 100%

Didn't realise how blunt the old cutters were my time spent shaving is now almost half what it was and the shave quality is excellent. If they last 2 years as advertised this will justify the expense..
