for Phillips Shaver Head SH50/50 AquaTouch Sensotec HQ8 Spectra Multi Precision

From the outset, these are a poor replacements for genuine Philips heads. Doesn't cut anywhere as close as genuine heads; you can tell from the noise that it's not cutting properly, and multiple passes have to be made to get an acceptable result. Inside cutter design is not the same as Philips.
Don't fall into the trap of thinking that this is 1 pack of 3 heads, it's not, so for the price of 3 are not as cheap an alternative when compared to cheaply sources genuine Philips.
If you don't agree, you haven't tried genuine heads for far too long.

Good
