The original Pocket camera was on the fragile side, but when used with care was very reliable. The new Pocket seems more robust. On the other side, Ursa Minis are fairly well built also, but all if the, can be broken, if you do not use some care. The Little Micro was a fairly solid build also, but it did not have any doors, and only one nice tight fitting battery latch.
Too bad BM didn’t follow through with a little more robust build on the new Pocket 4K, the devil is in the details...
Cheers
