I’ve had the Arc for a couple of years. It’s great but there are much cheaper options if you don’t need the timer. At first I used the functionality but now literally just use it in weighing mode.
It looks nice though and is very well made.
Auto-tare when you put a cup on it
Auto-tare and start timer when you put a cup on it.
Auto stop timer when flow finishes
I’ve found the auto functions can sometimes behave strangely and the timer will just stop mid shot inexplicably. Sounds similar to your Timemore.
Not sure on the copy aspect but I bought from a well regarded coffee retailer here so I assumed it was ok.
Overall a nice scale but if you don’t need the auto timer and tare, much much cheaper options available.
