For the moment, pretty happy with the hub. The cog is a bit frustating to install and there's some back and forth during shifting setup (when you're not used to) but at the end it's working fine and not so difficult.
It's my first IGH and I have to say it's a real pleasure to use, it's very silent and smooth compared to cassette/derailler. It's also not so uneffecient compared to what I expected and heard. It takes some time to get used to it, once you're confident with it, it's very nice and relaxing to ride.
The overall build quality is pretty good considering the price, Nonetheless some spokes were marked and I don't think it's due to shipping. The DT Swiss rim is solid (I already got some of those on previous wheels). Of course it's pretty heavy but considering the reason of this wheel is to limit maintenance that's not an issue at all.
