OK - just wondered 
I've just had a third mod get a problem! The new sigelei Mini I started using was constantly getting stuck on the firing button. Sometimes I didn't notice, and the battery would flatten overnight.
Yesterday, it wouldn't recognise the tank & coil, and was firing all the time (tank fine on a different one) so into the bin with it - I don't trust dodgy electronics!
I'm using another of my spares now!
