I came here specifically to see if anyone had any thoughts on this much smaller signal mirror (apparently no one has one yet though). Any concerns or thoughts on a smaller sized signal mirror? Would you switch it out for the larger model?

Ideally you want the largest mirror possible the more surface the bigger and stronger the flash.
That said if it gives off a reasonable flash the mini would be better than no mirror.
Recently someone signaled help with reflections off their cell phone screen.
