Better than I expected.
I’m so happy I bought this item it’s very good for training tool
Great and easy to set up power meter with FindMy included. Can’t wait to track down some thieves.
Excellent fast shipping and comms, power meter easy to pair and calibrate. However power meter was marked, doesn't affect performance though.
Not cheap, but probably the best value power meter you can get. Top quality and very easy to install (though you may need a crank installation tool depending on your crankset, e.g. a "Shimano Crank Installation Tool for HollowTech II"). Integrates seamlessly with my Edge 830 computer, and has added a whole new dimension to my training!
