I ordered this off Amazon to be able to use my HTC Sensation at the Gym as my old Zen mp3 player has bitten the dust and it seems a bit mad to buy a new one just for this when i have PowerAMP installed on the Sensation.
The Sensation is a snug but easy fit in the armband and appears to be held very securely.
There is a thin flap at the top and access holes at the bottom for headphone leads and access to the power button . The armband itself is a comfortable fit and seems to be well made. I can confirm that the touch screen works well throught the clear plastic screen. Only slight snag is that the volume control buttons are hidden and require some groping about and a firm push therough the case - this isnt a problem for me as i have a volume control on my headphone lead.
Not a lot else i can say about it really !!
