Perfect fit, locked in, light and low profile. It would be nice if it had a hole or loop or ring to attach it to my drone bag during use, but it doesn't matter. It would also be nice to be able to check the battery level, but at the same time you still have to remove the cover to get to the power button, unless it has a sliding door or something; but you end up with parts that can break or get lost. Serves its purpose and has a good fit and finish.
