Query: Terrible!!

So I bought this for soapmaking, and I didn't realize the temperature only goes as low as 100. That's fine, that was my own fault. But the temperature is definitely off by at least 10 degrees. The clip on the side for holding the thermometer secure is cheap and does nothing. It's not sealed properly, so you get fogging inside and it gets so bad you can't even read what the temperature is. You can't even wash these by hand, because they fill with water! What a waste of money. Learn from my mistake!
