I've had a Fantasea CP4 Pro housing for about a year and a half. The push buttons have always been very stiff. Yesterday I decided to grease the rods (from inside the case). Boy what a difference. The action is much easier and much smoother. I can even control the shutter half-push now. I used a small wire bent in a half-circle to distribute the grease around the rods. If you have one of these housings you want to do this if your controls are stiff.
