Krypt / Bullet Lines swivel racks

[Tmosely1]

Im considering the Krypt / Bullet Lines swivel wakesurf racks for my flight control tower and I was wondering if anyone is using them and had some feedback on the durability and function especially on the swivel.

I put a pair of the 7.7 with swivel on my fct2 almost two years ago. The swivels have to be adjusted just right to be smooth but seem very durable and have held up good so far. The speakers need a couple hundred watts.
I take mine off a lot because of where I store the boat, a quick release would be nice
