Decent and robust; but poor quality control.
Ordered 2 units, one showed with severe carcass deformation after inflating within recommended pressure. Thankfully Bike24 helped me out and send a replacement, which to my surprise also came defective. Fustrated, I notified Schwalbe about this, they were very surprised and asked me to return the tyres via Bike24. Once again Bike24's awesome customer service made all this hassle easy for me and they managed to send me a 2nd replacement, this time without any visible defect (so thanks a lot for that!)
After some rides, I can tell they make my training wheels feel surefooted and solid, although they don't like to accelerate much (for obvious reasons) Cornering is reassuring but feels a bit wooden on rough surfaces, no matter what pressure.
