Dale,
we've been using the mesh cassettes for years with good results. We used to
use tea bags and wraps, but like you, we were loosing specimens.  As far as
the processing of the tissue, it is fine.  We receive specimens like G.I
biopsies, endocervical, cervical, heart, lung.  All these process well and
we have decreased our lost specimen incidents.  The only problem ( and it's
a small one) is sometimes the paraffin doesn't drain out completely and when
filling the cassette, you can get bubbles under the cassette.
