My personal experience was not great.
The item seemed well made, and fit my Braun Series 7 (Model 5692) electric shaver perfectly.  My personal experience was that while it functioned normally, the shave it gave was not very good.  The first (and only) time I tried this I ended up using my genuine Braun head, which had been in use for exactly 6 months, to finish off my shave.  This head just left to many whiskers for me to be satisfied.  Granted, the cost is about 1/2 to 1/3 the cost for the genuine Braun replacement head, but if it functions like I experienced, it is a false savings.
