I noticed the first footswitch can be jiggled up and down a bit, while the other two are tight.
I wouldn't have noticed if all three were like that and it probably has no consequence on anything long-term, but thought I would ask if others here have the same/if it matters.
All three of mine are tight.
As long as the loose one works ok I personally wouldn't be worried about it.
If it does worry you then maybe email the national distributor about it and see what they say?
