With the high cost of gas in the UK, unfortunately, the home's central heating system cannot be turned on very often. However, with the low temperatures, even with an oil-filled electric radiator, I couldn't keep myself warm enough to feel minimally comfortable.
That's when I found Heatka Hand Warmer, which solved one of my biggest problems, frozen hands. At maximum temperature, the first few days you think it's not hot enough, but then with time, you realise that the temperature is ideal. I imagine that to launch a product like this on the market a lot of research was done to find the perfect temperature range that would solve the problem without putting anyone at risk.
Excellent product. Simple, but it's making a big difference in my everyday life.
