prima product. Het compas is natuurlijk niet zo betrouwbaar als een gerenomeerd model, maar het funtioneerd als back up

passt in mein Badehosentäschchen, sodass ich beim Schwimmen in kälteren Gewässern (10..15°C) immer weiss, wie lange ich "drinnen" bleiben darf (Gefahr der unbewussten Unterkühlung - Körper-Kerntemperatur!)

Just what I need to have a small temperature gauge to put on zip of rucksack.

Llegó incompleto. Sólo una tapa transparente que no trae nada.

As you can see in the pictures this item is definitely old, the black spot is inside the tube, dirt patches all over the place, seems like sitting on a rack since years, though I'm keeping it, compared the temperature and compass with my smart watch and the results were almost similar

Bought as a stocking stuffer BUT I used it to prove to the car repair shop that they HAD NOT FIXED MY AC IN MY CAR! Very handy little thermometer!
