Height selection on metric side has jumps of up to 3 centimeters lmao.
Too lazy to look, but given 1 inch = 2.54 cm, my guess is the tool is written in inches, and just rounds those values to the nearest whole cm, thus alternating between 2 & 3 cm increments.
Grove has become my go-to storefront for general household goods - they have a solid selection of generally reasonably priced jtems, and a strong aversion to plastic. They’re by no means perfect but I feel a lot better with them getting a cut of my money than Bezos.
They’re not going to have the billions of niche items on Amazon, but they’re pretty great for my needs.
