What to Compare Before Buying

Using It in Practice
The shake awake function means the sight enters a low-power state after 2 minutes without motion, then returns to the previous brightness setting when moved. That makes the brightness setting you choose part of normal use, rather than a one-time adjustment.
The 12 settings also give a simple way to match the dot to changing light levels. The lower settings are described for dim or rainy conditions, while the higher settings are described for brighter conditions.
Before You Decide
Confirm that your rail is 21 mm Picatinny before choosing an offer. Check whether the 2 MOA dot and 12 brightness settings match the way you plan to aim. If the CR2032 battery and shake awake function matter to you, make sure those are the features you want in this optic.
