What to know before buying

Listing details to confirm

The listing names 2 AA batteries in the title and feature text, but the explicit included-components list names only the GLM100-23 measure. Battery inclusion is therefore uncertain for the selected listing. The listing also describes two-button operation while separately mentioning a click wheel and additional keypad controls, so the exact control layout is inconsistent. Confirm the selected package and control configuration before buying.
