I use their magnetic in-body filters and I’m pleased with the performance (have not had occasion to use the 3 stop yet, only the 6 and 10 stop versions).

And to answer my own question, the drop-in filters are amazing, no tint in ND10 and ND15
The only issue, which is not an issue, is they need a bit of pressure when sliding them in the Canon RF-EF Adapter, they don't slide as smooth as Canon's own filters.
