I got a power crank arm for my MTB to help with my training. This one was easy to put on as I already had a XT crank, unbolt one and bolt the other one on. Paired with my garmin 830 and off we went! Came really quickly.

First ride looks promising, everything as expected
Arrived well packaged, quickly and in perfect condition. Works exactly as it should. Will be getting another for my other bike as soon as I can
Just what I wanted. Happy to buy a refurb to save quite a lot! Delivery as promised, really good service
Quick and easy install, affordable left-crank power meter for Shimano XT/SLX grade mountain bike drivetrain.Recently I upgraded my aging 3x10 SLX cranks / XT derailleur MTB drivetrain to a 1x12 by replacing chainrings, shifter, rear derailleur, cassette and wheelset. However as I was riding more on my indoor trainer every day last winter, I decided it would be a good idea to get ahold of a power meter so I could get Power-based workouts and readings instead of just estimates based on wheel speed and trainer model information.Connecting via Bluetooth to my cell phone has been very easy and the connection is very stable.I have not had yet I wait to verify how I create the readings are but I suspect they are much more precise than speed based estimates.The ANT+ ... MoreQuick and easy install, affordable left-crank power meter for Shimano XT/SLX grade mountain bike drivetrain.Recently I upgraded my aging 3x10 SLX cranks / XT derailleur MTB drivetrain to a 1x12 by replacing chainrings, shifter, rear derailleur, cassette and wheelset. However as I was riding more on my indoor trainer every day last winter, I decided it would be a good idea to get ahold of a power meter so I could get Power-based workouts and readings instead of just estimates based on wheel speed and trainer model information.Connecting via Bluetooth to my cell phone has been very easy and the connection is very stable.I have not had yet I wait to verify how I create the readings are but I suspect they are much more precise than speed based estimates.The ANT+ connection to my Garmin bike computer seems to work fine too.I have been using Zwift for over two months now and this power meter seems to be working flawlessly, but then again I cannot attest about the accuracy since I don’t have any means to validate the readings, but I have no reason to think it’s off. So far I am very satisfied with the product and I have already pulled over 40 hrs on the original CR2032 battery and it seems to keep going strong.
Works fine, my left side is stronger so think it is inflating my power output, so not comparing it to other sources of data. Stages app is a bit clunky on my phone.
Simple to fit, though it would have been better to have some instructions.Connecting to my Garmin and Stages App were easy and software was updated easily.All works perfectly, can be calibrated through my Garmin after connecting.
My first power meter , works as expected , don’t train but just use it to monitor power on climbs , was an impulse buy , more out of curiosity than need
