I use the holder with a Galaxy S3 and am completely satisfied. Even with a good sized phone the magnet holds the device firmly in place and even then does not dissolve when you press the Home button on the phone. The counterpart of the mobile transmits to something that can be mobile but still continue without problems in the Mumbi Handytasche click it. As the holder needs quite a bit of space I can install also close to the driver's mobile phone finally.
Only suggestion: Great would be a magnet is strong enough that you do not have to take out of his shell mobile phone.
