So, basically, we narrowly avoided a fire that would have started in my master bedroom, with us sleeping there. I've since used this to put every outlet in the house under load and checked for heat. I looked into thermal imagers, but those are expensive to even rent. This is accurate to record the temp of a grill top and many other surfaces you probably don't want to touch test.
It's a fun toy, and maybe a lifesaver. I'm not saying you need one, but if you have disposable cash around, think about it.
The HF sale flyer I just received in the mail yesterday had a coupon for those at $24.99. Not sure if the HF storefronts have the same multi-page glossy coupon flyers on-hand, or if it was a mail-only promotion. Might be worth checking a store if you have one locally, or watching to see if it goes on-sale online at the lower price in the near future.
I was considering one for checking the temperature of solar ovens and items being cooked in same.
