A Nest Thermostat, for my mom and dad.
My mom and dad have done so much for me, but neither them or I can buy a replacement for their unusable thermostat, due to monetary reasons.
Their current thermostat is VERY hard to use, and even a tech-head like me cannot use it. They just turn the AC off, and use several fans and heaters around the house.
I want to get them a gift like this for Christmas, but I cannot afford it. They've done so much for me, and have ensured that I would have a bright future. They still refuse to take any extra money I have, or buy them a meal. They donate to charity regularly, but don't give themselves the luxuries that many other people have. They also work relentlessly, and both still work when many would retire.
Good luck to all, and thanks for providing this opportunity, LTT team!
