Pros: Fits a Quest 2 with an M2 strap connected. I also have a battery strap at the back but had to take the battery off in order for it to fit. All in I have the HMD, controllers, two battery banks, a small pouch that has my IEMs inside. I feel there's still some room in the books and crannies for more. Cons: None really, but this is MUCH larger than the Oculus case. Don't be surprised as it fits most aftermarket head straps.
