Very stable and easy to see - Reptilia Bubble Level AUS Accessory

This is not tiny as some other reviews mentioned. I had a Vortex one before and keeping that thing stable was impossible. This one is fast and very visible (at least if you set up on the back position of the AUS mount). Since there is no adjustment, I was worried if it would be perfectly leveled with the mount. But being Reptilia, it was.
