Good product bad customer service

Love the fat sacs but their customer service is terrible. They charged me for 2 items that weren’t in stock. Then sent me two fittings that were the wrong size. I’ve emailed 4 times and no response. Would not buy from these guys again.

Thumbs up

This product gets two thumbs up from me!! I would give it more if I had more.

Just what I needed

Fits perfect inside centre storage locker on 07 AR230 jet boat and leaves enough room to still store a two person tube, 4k blaster ball and some dock lines and two fenders.


Perfect for the back lockers! Can't wait to get out surfing ! Fast delivery:)
