I need something new at the moment. I originally bought a Vision spinner II, But that was crap out of the box and only lasts one day on a charge. And that's using maybe 10 times throughout the day.

The place I bought it, "Doesn't do returns" so I'm screwed on that. I'd like something that is the same style. Nothing big or odd shaped as I use a Gladius 2 tank.

I agree with the rechargeable 18650 battery comment. Mods are cheap, and if you break one, you just take out the battery and pop it in the new one.
Batteries are the critical component. Make sure you get quality!

I'd recommend these 3 first:
Sony VTC6 (VTC5 and 4 are good too, just different mAh and CDR values)
Samsung 30Q
LG HG2
