I really hope there won't be more last minute changes and fixes to do. You can't help but feel sad when you think about it's "soon" going to be a year since this was funded. Yes, I'm fully aware how kickstarter projects work for anybody who's going to comment on that.
However, for your sake bst, I really do hope this mouse is flawless. I still to this day think if you'd been able to launch this back in December/January it would have been a huge success, but now with everyone craving low weight and some of the bigger companies jumping on the bandwagon, It's going to be harder for the Astrum to fit in. I'm sure people who care more about the shape will love this, and to be fair, the current weight estimate isn't horrible by any means, I find it just fine.
At the end of the day, I personally am expecting a "perfect" mouse, which means none of these issues, to list a few ontop of my head;
No creaking shell, no matter how you squeeze/hold/press.
No faulty activation of side buttons if you squeeze too hard.
No double clicks, massive sidesway, too loose M1/M2.
No issues with the sensor/firmware (No updates required after you get the mouse please...)
No panels being broken, bent, too big, too small, not fitting.
I'm sure there's somebody out there that can think of plenty more, but I really do hope whoever you're going to be working with now to send out stuff to backers, that they actually deliver on time and it's not going to be a situation of where people will be waiting months for it to arrive, and backers should be getting this mouse before you put it up for sale, considering the waiting time they'd had to go through. I may be biased of course.
Just my 2 cents though.
