Fantastic build quality. After swapping the clamps to the smaller diameter ones (included) it's very stable on my c line advanced roller rack. A good few pockets, a great main compartment with compression strap, a removable bright orange mesh zip bag, built in rucksack straps and securing strap to wrap around the seatpost. While not fully waterproof it does come with a bright waterproof cover.
Wearing flipflops I had heal click. But wearing my normal shoes or Shimano MTB boots no contact. But there's not a lot of clearance.
For 137 euro (it was 173 the day after I ordered it on Amazon Germany), it's great value. Very impressed.
