Overal a great product for the intended use. I would typically only get about 2 hours on a tank and needed the extra gallon of capacity the IMS tank offered.
Looks are not bad considering the extra girth but on the trail I would not notice anything I don't think.
My main complaint is fitment. The shrouds do not line up at all. What I ended up doing is pull the rubber frame wraps off that protect the original tank from rubbing against the frame. This made it much closer but still a pain to line up.
A good way to set the plastic is to get it all lined up and then use a heat gun to kinda "reform" the plastic while bolted down. Leave it sit till it completely cools and that helped me a ton!
I have not checked for leaks yet. But I will in the next week and let you know.
