Comment from the Wind Lounge team:

The Unifiber Windsurf Uphaul String is basically an ordinary Uphaul String. It is flexible, offers good grip for pulling the windsurf sail out of the water and provides few surprises. Exactly how a Uphaul String should be. However, cheaper materials are used for the tabs than for the Unifiber Uphaul String "Luxury". 

The Wind Lounge team gives this product a conditional buy recommendation. If you can spend €3.55 more, we recommend the Unifiber Uphaul String "Luxury". This is more wear-resistant. 

We recommend checking the Uphaul String for wear at regular intervals. The strap around the mast extension in particular tends to slowly wear out after prolonged use.
