Apex calcium probe... do or don't

[coralcruze]

anyone using the apex calcium probe... its it worth the cost? does it maintain accuracy? Is it a PITA to use and keep calibrated. Just wondering what the concensus is out there on this piece of equipment. reason I ask is that I find myself testing alot these days and it would be nice to check levels at a glance. so is it all what they say its cracked upto be?
