Hi Gary, ive had the mod around 24 hours and so far so good. It's the best mod I've owned by far. The build quality is superb, I can't find any imperfections anywhere. The only issue I'm having is I'm getting the weak battery message but it looks like that's a common problem with the DNA75 board. I'm not sure if it's down to the batteries I'm using not being powerful enough. Hopefully I can find out how to rectify this and then I would consider it to be the perfect mod. I'm currently using the ijoy captain tank
