This is the Kickstarter page for the Chilkey Glacier L—the mouse I reviewed as a legit Superlight alternative. If you want the light 47g build, PAW3950 sensor, up to 8K polling, and that little on-mouse screen for battery/DPI/polling, this is where it’s listed.
Pros
+Budget-friendly price compared to the Superlight
+Extremely light at 47g
+Up to 8K polling and up to 30,000 DPI (PAW3950 sensor)
+On-mouse screen shows battery, DPI, polling, and connection mode
+Stock PTFE skates glide very smoothly
Cons
-Battery life is lower than the Superlight (~60 hours vs ~100 hours at 1K polling)
-Build isn’t as tank-like as the Superlight; side can actuate a button if squeezed extremely hard
