Hello,We purchased one of your wireless meat thermometers through Amazon in May of this year. I have only used this unit four times and the power button has failed. I cannot turn it on/off. Right out of the box we had difficulty turning it on. It took a lot of force applied to the button to get it to turn on. Now the power on/off button appears not to work at all. Please let me know if this is something that will be replaced under warranty. It did not suffer any damage or improper use. Thank you.
