## Customer Reviews

### ⭐⭐⭐⭐⭐ Excellent fin set at a great price
*by J***. on November 18, 2018*

Outstanding fin set. I have a new board and was trying out different fin sets a my local break 2’-4’ and punchie. These fins were the last set I installed and what a huge change in how the board handled. The previous set was $110, and no comparison to these fins . Would highly recommend.

### ⭐⭐ Bad fit
*by R***Z on March 8, 2019*

The material is good, but the shape isn't. I had problem with all of the 3 fins. Non fit well and I tried in 2 different boards. Even after a bit sandpapering.

### ⭐⭐⭐ Three Stars
*by M***S on April 25, 2017*

great material but does not fit perfectly on the base, worth the price
