Reviewer: A viewer from Ferndale, WA US
I bought this thermometer to monitor the temp in my greenhouse. I had bought another manufacturer's thermometer but had to return it since the max and min markers would not reliably stay put and I couldn't trust what they were telling me. So far, the Sper has been a real champ - easy to read, seems to be accurate tested against another thermometer I trust, easy to reset. I highly recommend this model to any cost conscious buyer who just needs a basic max-min registering thermometer.
