Fits right on my Braun Series 3 380 (type 5773). Attach staking, new head shaved and already the good again. On the site you can see Brown the right spare part and should of course absolutely do before ordering.
I had my shaving now about 2.5 years (from the scope of delivery). The shaving time now has been a marked change, therefore, a new part. Now the face is also flat.
