I was looking for a hard case for my Phantom 4 and found this one. It was a bit of a concern as the photo doesn't show the inside. It arrived yesterday and I was surprised it holds both my P4 and P3. The battery compartments are slotted for both. It's got plenty of room; my only "disappointment" is that it only holds three batteries plus one in the drone itself (not a big deal to leave it pulled out partway, I guess). Not bad for $200.00.
