We had the tape coverslipper for several years, and while no problems occured 
immediately, problems did develop over time. The tape lifted on about 200 of 
the teaching slide sets. I was not a happy camper when I had to recover them 
with glass. Some of them were beyond help and I had to re-cut about 100. The 
pathologists never liked the tape from day 1 because they said the resolution 
was different from glass (makes sense to me) and they could never get a sharp 
photograph. We do a lot research and teaching slides, so I switched to glass 
coverslipper about 5 years ago. I don't know about the new ones, they might be 
much better.
