My experience is that most case manufacturers take an existing case and rebrand for another device simply by putting other foam in it.
That’s why I chose Magma Bags for my BigPrimes. Top of case = top of device. Really nice fit. They took time and effort to fit the specific device it should held. Swanflight is also very good.
