Bests & Worsts Reviews from Amazon

Always good to have a thermometer on hand. Two years after buying this one, I needed it. Consistent readings every time: POS, POS, POS...I changed the batteries -- POS, POS. I took the batteries out and pushed all the butttons to discharge any capacitance--POS, POS. I left the batteries out over night -- POS, POS. I tried new lens caps, guess what? -- POS, POS. You are throwing your money away on this purchase.
