## Customer Reviews

### ⭐⭐⭐⭐ 







  
  
    Easy to install and accurate.
  

*by S***S on Reviewed in the United States on September 27, 2018*

I say this one is more accurate than the stage power. I have this on one bike and the stage power on another bike.  The reading on this one is more steady and accurate.  Install is easy too.  Problem is, it's only compatible with a few crank arm.

    Buyer beware
  

*by A***R on Reviewed in the United States on May 11, 2018*

Followed instructions exaxtly and let dry 4 days.  Literally fell off on first ride.  On a trainer, not even an outdoor ride.  This product is inferior, do not buy.

### ⭐⭐⭐⭐⭐ 







  
  
    For the price of the meters you can hardly go wrong and I love mine.
  

*by G***. on Reviewed in the United States on June 9, 2018*

I have owned these since indigo days and I have had very few problems.  They have made some changes to help with all the problems I had, and always responded promptly.  For the price of the meters you can hardly go wrong and I love mine..... Slow down take your time and follow the video instructions and you will be fine....  I have moved them from bike to bike as I had to get new sensor from Watteam when I did but they shipped those out to me fast....Can you get easier power meters to install, Yes but you pay 3 times what you do for these... I give these and 8 out of 10....  But worth every penny and will buy again...Oh and I don't write reviews but, the hate was so strong.....
