What kind of thermometer do you use for your lo (armpit or ear)? And what brand?

Using armpit thermometer - infrared ones (scan forehead) aren't accurate (especially for younger ones) because LO's foreheads are too small to get accurate readings, ear thermometers wouldn't work with active/scared LO and would just risk hurting them if they struggle while you try to get a reading. I can't remember the brand but I got it over-the-counter from pharmacies like Guardian/Watson's, it's in a white box with green words all over :)
