Yessss

Recently changed homes and as a bike food courier I wasn't familiar with the surroundings. Got this so I can glance at where I am when delivering.
It's very spacious and i could fit my small hand pump, keys, wireless headset case, hand sanitizer and obviously my phone. This is a double edge sword because your thighs might hit the bag. I am tall(192) and a bit overweight (92kg) so my bike frame barely properly fits me. Because it's a road bike i tend to have my legs very close to the frame so sometimes my legs would slightly touch the edges of the bag.
It was easy to strap it to the bike and doesn't seem like it might go loose. The touch screen works great but be careful while raining as there might be some wrong touch registration. Nothing that you can really do about that. I was still able to press the side buttons and lock/unlock the phone. I have a 5.7in phone.
Overall a good buy for the price.
