I have mini prog and cas3+ solder free adapter no problem, first read was ok , writing also. You must clean pin position before put the adapter on pcb.

Done many Cas3 units with solderless adapter and no problems at all. You have to take your time cleaning and preparing all points on the unit (around 5 minutes). Sometimes its tricky to connect adapter properly but definitely worth it.

I just used mine on cas3++ it worked, but it took a lot of adjusting and cleaning to get the connection. next time ill have to do some deep cleaning first
