Review on Enhance Precision with Presto 85771 Steam Gauge – Pack of 1 by Sandy Johnson

UPDATED REVIEW - 3rd order/replacement/exchange and 3rd time test failed at my county office. Completely new out of the box. Maybe they're from a bad batch, aren't they? I don't know, but other sensors have been tried and tested on other people, so we're pretty sure it's not the expansion office's test device that's at fault, just the sensor. Revain was great at bringing back the first two. I hope to get a refund and not an exchange for this item. -- The item arrived defective - the County Extension Office inspected it (free of charge) and returned it as inaccurate. Sending it back for a refund even though I want an exchange. The extension office said that with the best brands it "happens sometimes", but that seems like a good indicator, so let's try again and hope the second try is enough :)
