Smart bathroom and kitchen scales.
The Omron Body Composition Monitor (HBF-222T) retails for S$169, though I paid S$130 on sale to replace my decade-old Fitbit Aria. It measures weight, body fat, visceral fat, and muscle, then calculates body age and BMI.
My Hario V60 drip scale was laggy and bulky for weighing espresso shots, so I went endgame with the Acaia Lunar. Listed at US$250, I bought it from Daily Grind Supply for S$379.
I bought the Fitbit Aria from Amazon's Black Friday lightning deals for US$93.99, shipping included thanks to AmazonGlobal Saver. In Singapore it's S$169 on the Apple Online Store, so I saved S$51, though I forgo the one-year warranty.
I got the Tanita Glass Digital Bathroom Scale HD-382 at TANGS for S$78. Its large LCD with a blue backlight is handy when reading from above. I finally have my own scale, having previously had to weigh myself elsewhere.
