Bought this as I wanted to understand my work on the bike objectively, and to train specifically to improve hill climbs. Was delivered promptly as always by Tredz. It is very easy to fit (using Shimano crank installation tool tool), and upgraded using the app. Initially I had a few strange power spikes and battery readings. Removing the battery I found the contact was slightly tucked under a sticker. I pulled that back into place and put the battery back in and it has been perfect ever since - seems very realistic and reliable power and cadence data. Have already found it useful to look at power vs cadence vs how I feel vs speed, and also to see the power changes on hills. It’s not cheap, but it does seem good - overall very happy.
