Didn't expect any more but it would have been nice.....Since my Apera PH20 wasn't calibrating right, and I was reminded they have a 2 year warranty, I reached out to Apera....couple emails back and forth, answering questions, how old is calibration fluid, what do I store it in, how old is storage fluid, do I try this, do I see a bubble in tip etc. ad nauseam ..... they wanted proof of purchase so I told em it might take a day or two cause of going back through my emails to find the ebay receipt........got a email yesterday that they had closed the ticket out....seems like I won't be getting any warranty on it...... and I'll be looking for a pH tester other than Apera's
