I have one of these bought years ago (so no guarantee it’s the exact same innards as today’s). Not worth the money, because it sometimes misses counts and ends up displaying a number that is off by some multiple of 5.08mm.
These things chew through batteries because the “power” button just turns off the LCD, which barely uses any power anyway… The entire measurement circuitry is apparently still on. I have no idea how Mitutoyo and others with true auto power on do it, but the cheapies don’t do it properly.
They also don’t slide as smoothly as quality ones like Mitutoyo, Mahr, Tesa, or Sylvac. Not a deal breaker as such, but just not as nice to use.
I then got a vernier Mitutoyo on sale for something like $35 which works great, and eventually I’ll get around to buying some quality digital calipers. Those also come in various useful options, like different lengths, shape of the depth gauge pin (square for disability, round to fit in smaller holes), with or without the thumbwheel, bigger displays, IP rating (so dust or water ingress doesn’t mess up measurements), data ports or bluetooth, etc.
