I have three cases now (905, 910 and 920). 910 is for my Atomos Ninja V. I'd originally purchased the 905 for the Ninja and it would fit nicely, but I wanted to add some accessories into the same case, so I bumped up to the 910. I'll find a use for the 905 soon enough. I use the 920 for my GH5, batteries and lenses.
The cases are very nicely made and I trust them to keep my gear safe. The cubed foam inserts are easy to shape.
Nothing else to say except it's obvious these are going to last me as long as I'm still kicking.
