This is what I done exactly with my Philips S9000 and Panasonic ES-LV9Q as nowhere near good to Braun. Both returned after testing for a week. I doubt you can find better electric shaver than Braun after razor.
I bought the top end 9 series a while back (9390?) , found it almost useless terrible cutting quality, lasted about 3 days and returned it and went back to an old panasonic for daily use and wet shave for special occasions :)
Has been at £199 on Jan 2021 on Amazon. I bought one in February from eBay for 109, mangled box, but new and unused. Agree, it is quality product, but I liked my Series 7 more, as shaving head is smaller and better cut. Motor gave up on it after 8 years of daily usage, otherwise wouldn't swapped for Series 9.
Braun 9390 is going for £219.95 with prime free delivery eBay are offering same for 10 per cent less.Best one rarely less than this quality product worth it in my op
Good shaver but this price is fairly standard. I paid just under £200 for mine about 2 years ago. The button broke on my shaver but service from Braun was good and it was fixed under guarantee within a week.
