why newer philips shavers has less quality of shaving even with higher technology?

Hi Alex,
There doesn't seem to be many reviews on this site about Phillips shavers, but the one person that did review it had mostly good things to say about it. www.myshopping.com.au/RV--861_Philips_Micro_5000_HQ5426_Shaver
The issue with the older shavers having seemingly better reviews may be because in order to make a product have a more attractive price tag, the suppliers need to make it cheaper. Several years ago, the focus may have been more on quality. But because we now live in a disposable society, most products (not just shavers) are being made cheaper so you can afford to just throw it out when it stops working and buy another one.
There is a good selection of many brands of shavers, complete with reviews, here www.myshopping.com.au/PT--198_Shavers
