Reply to VCI 100 sensor adjust screws

Anyone reckon the 2 screws to adjust this are really flimsy/difficult to adjust.

If I turn them to full (max) the platters stick to red or delay on red before going back to blue. One is more prominent at doing this than the other.

Does yours do this? Im in two minds wether this is a fault or not.

If youve got one to Id really like your feedback on this.
