I bought a Mark5 5-25 Tremor3 Illuminated about a year and a half ago. Then I bought a 3.6-18 Tremor3 non-illuminated a few months ago. Honestly, I didn't even think twice about dropping the illumination on my second one. It's dope for sure, but I haven't ever felt the need to use it which includes probably a dozen sunrise/sunset hunting sessions and several range sessions at dusk. Also not to mention the hundreds of dollars more just for a few tiny dots to be lit up. Not worth it in my opinion.
