Bought this to use with pencil mics (DPA400X, Sennheiser 8000 series) on the road. Sometimes I need to travel to rather rough places (outdoorsy stuff) to go recording. I've had the case for a few years now, and it is well built, but I notice I heardly ever use it. Mainly because I don't trust the allotted padding for the mics, and think it is too bulky.
The plastic tubes (and the aluminium (?) tube they are in) are well built and feel very sturdy. The small plastic tubes are a neat and efficient way to store pencil mics. I like the hexagonal tops to avoid stuff rolling away.
Inside the big tube there are 3 small tubes that have padding on one side, which would compress against the mic. Then at the bottom of the big tube there's some more padding. There is no padding at the side. The 3 tubes fit so tight that they don't really touch the padding on the bottom. So they only rest on the plastic of the tubes. I'm more worried about the lack of padding to the sides (hard alumunium wall). there you're mics aren't very well protected for falls and shocks in that direction.
The 3 tubes inside a tube also make for a lot of wasted space, which makes this a less than efficient way of packing the mics (though more efficient that their brand's boxies). It gets rather bulky for 3 mics.
I'd rather get a small peli (or knockof), order some cuto to size foam and use that for my microphones. Or a normal plastic box with my own padding (I use pipe isolation). Packs down very small and offers a lot of protection, at a fraction of the cost).
So in the end, I wouldn't recommend this.
