I wanted this to be a winner and probably it is for a beginner. With normal seated cadence and sub 300w it is great, however when surging or “staying with a move” it greatly under reports power. That is not terrible in itself for the price point but if you utilize normalized power for judging condition late into a multi hour events it really throws this number off. Ultimately it was worth it for me to go with Favero Assioma dual pedals.Affordable power crank that allows me to use mountain bike shoes and petals and still get power readings on my Garmin. I changed to mountain bike shoes and petals to prevent nerve damage on the ball of my foot. In making the switch I was unable to use my power pedals. This power crank solved that problem so the power meter is on the crank not the petals. So far it works great. The only complaint is the charging points are hard to see and make sure they are charging. However, the benefits of the power crank far outweigh the charging design. Highly recommend.Bought this after checking reviews from cycling YouTubers. However, shifting was so bad from small to big. I had no idea how they didn't mention this problem. Anyway, I googled it to check other reviews n noticed there are lots of complaints about the shifting problem. I emailed the company to check this. I was told that they redesigned chainrings last yr. Seems like I got the previous gen of crank.This power meter is very accurate and easy to set up using the Magene utility app. Once you get it on your bike charge it, download the app, calibrate it and enjoy.The cranks are not very stiff, and the chainrings are not replaceable. So you have to replace the entire spider and rings when they are worn out.Very nice product! It is almost as good as Shimano R8000, but the price is much lower, very good budget option in my opinion. I would highly recommend!Lleno todas las espectativas para mi como ciclista profecional luego de 2 meses de uso continuo y entrenamientos especificosEs esxelente en relación, calidad, precio.I have used it for 3 rides so far. It connects perfect with garmin 830 edge. Before i bought it i was a bit concern about 12 months old reviews saying the left pedal had not the correct stiffness. Mine is fine, i cannot see any difference from my dura ace crank set. I would have liked to have more than one screw to tight the left crank pedel arm. Moreover i cannot see any problem so far.Die Verpackung war schon Mal an 2 stellen Fett beschmiert. Also wahrscheinlich schon Mal kein neues Produkt.Kopplungsprobleme.Das linke Pedal Loch Schein nicht mittig in den Kurbelarm gebohrt worden sein. Läuft unrund.Medidor de potencia dual (uno en cada biela) con doble protocolo inalámbrico (ANT + y Bluetooth) que incluye a platos, compatible para eje de 24mm. Muy contento con la compra.Ottimo misuratore di potenza per chi non vuole spendere tanti soldi. Funziona benissimo, molto gradevole esteticamente, non sarà sicuramente come le marche blasonate ma per meche non sono un pro va benissimo.
