Wish I purchased sooner

The item is ideal for my cycle rides saves me taking a rucksack. Great quality and inside pocket is bigger than expected. I'm able to put all things needed into this bag. The phone view is great for fitness apps and sat nav.

Very useful bike phone bag

The bag is well made and great value. It fixes well and stays secure in place when on the road. Whilst you may become conscious of your knees coming close to it when you are out of the saddle climbing they don’t actually hit it, so no problem. Phone responds to touch through the window but not fingerprint. It’s very useful for carrying and using a charger pack to extend your range - enough room for other stuff even a paclite jacket.

the only you could set it like in the pictures without it moving around is if it's really full. in general you have to strap it really tight and gets deformed and still the knee might move it. most phones the turn screen on is on the side so if you dont lock the screen and put it there the map app will recognize the touch and do something. if you lock the phone the button is inaccessible. it plastic top reflects more light than i wanted. you have to have the screen with really high brightness and sensitivity also higher than default. Since they are straps i guess they ware out easily specially against the elements. The security vs time it takes to strap unstrap is also to be recognized. risk the robbery or waste time removing it? overall it's good enough for the £5
