Yeah that's quite true, I think i'll go ahead and do so to be honest with you, it's not a huge deal, but it's just a slight issue that I have at this moment in time.
My biggest gripe at the moment is the left mouse button that feels kind of 'loose', while the right mouse button is perfect and is how it should be. Everything else is great and one of the biggest improvements is the m4/m5 buttons, they feel AMAZING now.
So it's not just me then? that's good to know. It's a little annoying though, it wasn't at-all prevalent on my old FM2015, so not sure why it's prevalent now. I was tempted to send it back, but I'd rather not go ahead and do so as I'm just not a fan of waiting.
