## Questions & Answers

**Q: Want to make sure orientation of right and left fin is from the rider's perspective looking down at the top of the board, correct?**
A: Great question and most people do not know. To determine the fin side, you lay the board FACE DOWN with the fins toward you (facing up).  In this perspective the RIGHT fin is the RIGHT fin.  Call us if you have any questions.

**Q: Is it only one fin for $45???**
A: Yes it is, these fins are pretty expensive.  They are carbon fiber.

## Customer Reviews

### ⭐⭐⭐⭐⭐ 5.0 out of 5 stars







  
  
    Look at it from the bottom to determine side of board
  

*by P***A on Reviewed in the United States on July 23, 2021*

Item fits and works but I got the wrong side. I wish that they would have told me on the listing that you have to flip the board over and looking at it from the bottom to determine whether you need a left or right fin.

### ⭐⭐⭐⭐ 4.0 out of 5 stars







  
  
    These are nice to change quick but beware they fall
  

*by L***N on Reviewed in the United States on August 27, 2022*

Love this idea but wish they could maybe float. If you accidentally hit the fin backwards it will pop out off the side of the boat it goes and it’s gone it has happened to me twice in the 1-1/2 years I’ve had the board I guess it would be different if they had a Cheever option.

### ⭐ 1.0 out of 5 stars







  
  
    These fall off so easily and you will be replacing them at $40 a pop
  

*by R***M on Reviewed in the United States on July 18, 2021*

The locking mechanism for these fins on your Ronix board is terrible and they will fall off frequently. As such you will be paying $40 a pop to replace these fins only to have them fall off again.
