Review on ☕ Matte Thermo Mug Bobber Tumbler - 0.47L by Felicja Pawlak ᠌

The first minus that infuriates in new products is glue. A cardboard hoop mounted on a mug leaves behind three healthy blots of glue, which is difficult to clean off (and it’s a pity to scratch a new thing with a rough brush that does not yet have a kotsek). The top of the mug heats up noticeably. For keeping warm. I used two devices: a thermostat and a kitchen thermometer. I poured boiling water at 100C, screwed on the lid, let it warm up for 5 minutes, drained the water and again filled it with 100C water at risk (you need to fill in less, because when twisting, the water still goes over the edge, the risk is not measured. After 3 hours and 40 minutes, he made the first measurement, the water was 75C. After 2:20 I'll see what happens, but I think the temperature will drop a lot, because I opened the mug for temperature measurements and the accumulated heat came out by itself. Since centigrade drinks will not be poured into a mug, I'm not sure about its ability to keep drinks at least warm, coffee drinks based on espresso get into the cup already 65-70C. A little later I will supplement the review with new measurements, but in general, the wow effect, unfortunately, did not happen. After 6 hours the temperature was 68 degrees. I poured hot coffee from the funnel according to the scheme with preheating, I will add a review later
