We have been using the WAW system since early 2018, so by this time of writing about 1.5 years.
Grafts quality is really good, in fact at par with manual extractions for most of the time.
In some very special cases however, we feel it is required to go back to manual (this can only be determined during the treatment).
As we have performed manual FUE since 2004 we have no problem reversing to manual if required.
Here is a recent example of a client that wanted to have a conservative approach and with just 1700 grafts.
This result was achieved by using the WAW system in combination with the highly experienced hands of our team members.
