Review: Really good buoy but! The line is really short , as it is described yes i know but just keep in mind this is to short for any 10m below dives, for a safe and confortable deployment.
Review: The reel is very small. Made for a child's hands and the line is very thin. Says it included a double ended clip, but I didn't receive one. Now I have to go buy that separately. I at least hope the smb holds air. I like the colour so i gave it 2 stars instead on 1. I would return, but I'm off to the carribean in days and don't have time to order a different one.

*by A***A on 16 December 2021*

Used this snorkeling. Solo trip. Was great until I dropped it and it unspooled all the way to the bottom and got wedged between rocks. I had to cut it and leave. Wish it attached and could retract. I kept getting it wrapped in my flippers when I surfaced
