My experience is fairly similar
I got one nearly new from eBay for 150 for that price it’s quirks are forgivable but if I’d had paid the new price 230 > 250 I think I’d have taken it back.
It’s my first gps computer and the nav and computer functions are good and once you have the correct screen up it’s fine
The issue is the gui and screen
It doesn’t work with gloves and even with just fingers you can be tapping and nothing happens.
The infuriating thing is that this would be forgivable if there was a physical button to move through screens (ie between navigation mode and stats / speed
At the moment if I’m using it to navigate and I want to check time of day or distance I have to stop take glove off and hope that it wants to recognise my finger.
I thought it might just be that mine was broken but other reviews seem to raise the same issues.
