Greetings,
 
I just purchased some Nassenheider Evaporators for use with formic acid.  
Does anyone have any experience with them and advice they may wish to give
me?  I'm planning on treating a couple of my hives with formic and the rest
with Apistan and see and compare the results.
 
Thanx in advance for any advice and comment,
