Review on GoolRC Digital Industrial Thermometer Non-Contact Temperature Gun with Backlight -50-380°C (Excludes Human Use) Battery Not Included - Grey by Miro Dadee

It took me about two months to receive it. As a result, I received it in the mail, put in NEW batteries, but it won't turn on. So yeah I shook it a bit and finally turned it on so I figured it was the contacts for the batteries. I had to seal the contacts with aluminum foil. I'm giving it one star because it's been working very well so far. But for the price, the long delivery time and the repairs I had to make. I would not buy this product again.
