2in1 Thermometer and Voltmeter

Good afternoon dear friends.
As the saying goes, it was evening, there was nothing to do. Although no, neither was it completely different.
A friend of mine wandering through the vastness of Aliexpress ordered himself such a thing and, so to speak, boasted to me

And am I worse than him? No, not worse, and I also want such a thing.
And after a month of waiting, I became the ownercool thermometer and voltmeter in one case. Everything works, though there is a small nuance - it is slowly gaining temperature. But for me this is not important.
True, I see it has risen in price to 436 rubles with a penny. It cost me 322 rubles. Or, nevertheless, the dollar rate jumps, or demand creates a price.
