Anybody running a dual sided Shimano 4iiii power meter?

Which model are you using? Is it the 4iiii Left-Side Crankarm with Podiiiium Powermeter for Shimano 105 FC-R7000? If I go one sided I am considering it as I found it with a good discount for 200€ / 220 USD.

Unfortunately I read that there are some issues with reliability.
