I used them for a few rides before the event, then for 9 days in 2018 during the event and haven't used them since then. These pedals measure the power in each leg independently and gives you a lot of data about your pedal stroke.
They have never been in a accident and are in very good condition. The item "Garmin Vector 3 Dual-sensing Power Meter Pedals RRP £789.99" is in sale since Monday, November 15, 2021.
