If only that were an option. No such store where I live, or in this country (that I'm aware of). At the advice of many here at BYC, I purchased an independent thermometer when I bought my incubator; turns out that the one I bought was more incorrect than the one in the incubator, and by setting my incubator to 99.5* F according to the store bought gauge, found my chicks hatching at 14 or 15 days, and almost all had medical issues... enough of them had problems (or deaths) that that whole hatch is isolated and will all be used for meat only. I don't wish to incorporate any of their health issues into my future flock. The store bought thermometer is a Microlife brand, shaped like a duck's head, and totally unable to calibrate... I cannot even switch it from Celsius to Fahrenheit. As mentioned in a previous post in this thread, all guarantees are void the minute you've paid for something here; they simply are not honored. The manufacturer's solution is to me to prepay both directions to ship the item to them...with a specific form that must be mailed to them... and their form specifically expects you to be sending the item from the USA. Incidentally, because I'd be having to send it out of country, I would have to pay TAXES (and shipping) both for exporting and then importing when the thermometer is returned. It would cost more to go through this whole warranty process, than I spent on the thermometer, and take at least a month of two. To put this into perspective financially... my neighbor rents his house, and the acreage it sits on for $35 a month, so saying that I spent nearly $30 USD on a thermometer that doesn't work has my feathers ruffled.
