Review: Muy bien - La boya es buenísima. Funciona perfecto. El carrete es más pequeño de lo que me hubiera gustado y el cordel utilizado no me gusto (por ser plano y se riza con extrema facilidad)
Review: Tel que vu sur la photo - Exactement ce que j'avais commandé. Reste plus qu'à l'essayer dans l'eau.

### ⭐⭐⭐⭐ Muy bien

### ⭐⭐ Nice, but cheap
*by I***O on 29 April 2024*

We used this for two dives last week, and on the second dive the nylon web that attaches to the line sheared and because we were 45' under the surface we didn't really have a safe way to surface and get it back. The current and wind have taken it away.
