The timer looks and works as depicted. It seems a bit bigger in person than I expected, but for the price it probably isn’t fair to expect smartwatch-level miniaturization. Along with the cube there is an exceedingly short USB A-to-C charging cable, and brief instructions that are reasonably understandable apart from tiny print.Using in gravity mode is simple—just set the cube with the desired countdown time (5/10/30/60 minutes) facing up, and turn the display up to pause or down to reset. The display powers off within a few minutes when not in use. Manual mode is more fiddly, operated via small faintly-labeled switches and buttons on one side of the cube. Labels could be more intuitive (e.g. the switch for choosing gravity vs. manual mode is labeled “off, 1, 2”, and start/pause is “SP/ST”), but in gravity mode this is fortunately a non-issue. All of the functions I’ve used (mostly gravity mode, one test of manual) have worked fine.I can’t speak to yet to just how long the built-in battery lasts, but after an initial charge and several hour-long countdowns it is still going strong.Overall, if you have use for a simple one-purpose timer and the four preset durations fit your needs, I think this is a reasonable choice and very simple to use. I ordered it to use as a meditation timer less prone to interruptions and distractions than a smartphone, and it has worked well for that. If you often need to set durations other than 5/10/30/60 minutes, there may be more convenient options out there.
