I have a 2 mode Aurora. I love it. I only use it on high and it runs for up to 60 minutes. If you need more run-time the two battery version gives you at least an hour and a half. But for $36 (plus $17 for 4 batteries, $5 for a mount and $10 for a charger) you get a VERY bright light. Aim it down.

Low mode is not useless. Low mode is nearly as bright as my backup Romisen. I have no use for the blinky modes but some people like them. They'll probably cost you $5 extra.
