Just my two cents from a Far South Texas lurker.

Bob sent me a CS gen at my request and it worked great until I somehow got 
water in the unit.  I sent it back & Ole Bob repaired it, sent it back and at 
no charge.  The unit works great, has a stirrer, and consistently produces 
clear 10ppm CS.   Just want to say my thanks to Bob for being such a 
charitable person who really cares for others.
Thanks again Bob.  Hope you stick around.
