Greetings and welcome from Hickory, North Carolina :)
I have a Lowes version of that same wireless probe you bought. It's the same probe that I paid a little more for based on where I bought it. Mine works very well and I have been quite happy with it. My suggestion is to pick up a box of 4 AAA rechargeable batteries for it.
