Review (3/5): Good Shaver But Not Worth an Upgrade
I am a 30 year Norelco user who also owns a five year old Norelco 6885XL which was the top of Norelco's line when purchased. In my opinion the new Smart Touch line that uses the HQ9 heads is not worth the upgrade. I buy new heads once a year, which makes my older shaver feel like new. The only real reason to upgrade a Quadra/HQ7 Norelco is if the batteries are failing--and there are numerous places now where you can have your dying batteries replaced.
Don't fall for "the latest is always better" line.
