Visited yesterday without charging to take pictures of the M-CHARGE chargers.
They have not yet taken down the signs that say the free chargers will be replaced by paid charger at the end of November 2023.
This was already the case when I visited back in 2021, but while the parking and chargers can be accessed anytime without barriers, there's a ban sign forbidding to park outside of opening hours. So you can use the chargers 24/7... at your own risks.
