TLDR: Great concept but Bad design.
All in all a $200 product and its replacements lasted about 1-2 months before tearing, ruining the seal.
And lasted 3-4 months total a piece before corrosion and the entrance was ripped.
My FLIP Zero and black editions regularly last 6 months before significant wear needs a replacement.
As one can expect, A FLIP that's soft and rumbles. I honestly couldn't believe what I was feeling. It's a shame it's longevity is extremely disappointing. You make one bad move with this and the seal is punctured and the experience ruined. The material around the internal side of the hinge is far to thin for how soft it is, a couple thrusts that aren't exactly straight and your member has torn through and is scraped by the hard plastic frame. I had this happen to one, and its warranty replacement. I used them both twice a week and I had them tear the same way along the hinges in less than two months.
Alongside that major design flaw with such a soft material was that QA was pretty bad on my samples. The screws on the end weren't fastened very well. Water does what is does and seeped through giving a very visible copper teal corrosion along the whole length of one wire. In my replacement unit, there was an internal tear along side another copper wire in an area I don't believe gets any action as its recessed away from the folds/bumps. This of course resulted in more corrosion.
