I have the smaller one that I got at Wally World a few months ago. I dont think it's an omega but it works great, I haven't had any problems with it. I spend alot of time in the wilderness and I have been getting away from batteries altogether. I am now battery free. I'm glad you posted this about the omega so I'll know what to watch for. I was considering getting one but think I'll pass on it. The small ones put out enough light for anything I would need and they seem to work well.
