About this optical differences I would like to ignore, if the shaving would vote. Unfortunately, I have now - 4 months after purchase - find that regular hair be pulled when the beard is left standing times for more than 1 day. Also with a 3-day beard, the previously acquired Combipacks had no problem.
Since my shaver after almost 5 years otherwise is still top, I am more than disappointed by the quality of this spare part. I suspect that part of the production was delivered to a supplier that does not offer the best Braun quality.
