Very good case, with enough space. It ties well and solved both my problem of supporting the phone and the available storage space for things that may be needed on the go.

I have been using it for about 2 months. I have taken 6 rides over 30 kilometers. It can fit a wallet, keys, snacks, and a thin shirt to put something dry after a long ride. The phone case is great and you can use it quite easily. However, if it rains, it is a bit difficult because it doesn't hold the touch well. The other issue is that it is quite bulky, it hits my knee sometimes when I pedal. I would recommend a phone case that goes on the handlebar and a case that goes either under the saddle or under the top iron of the bike, and thinner so it doesn't bother.

I bought it primarily to use as a mobile phone holder, but in the end, it served me better as a storage space. During midday when the sun is shining brightly, you won't be able to see anything on the mobile phone screen (maybe because of the calls it receives, as it attaches to the horizontal axis of the bicycle). I would say the materials are acceptable. It attaches well to the bicycle frame, but it won't stay in place during off-road rides (which is understandable due to the scratches it makes when attached to the bicycle).

The only disadvantage it has is that it doesn't stay stable on the bike. Everything else is fine

The bag is very high quality, however the reason I am giving it 4 stars is because it does not fit well on the bicycle frame.
