the holder for my Nokia have ordered 5800 ME and tested several times.
Here are my impressions:
Material: very robust
Article: 2 components, with suction cup foot and mobile phone holder to screw with click.
Mounting: suction cup and advance a little moisten (breath enough), then connect the mobile phone in the holder by rotation / click with the suction cup. The phone holds bombproof in the holder.
Charging Cable: spiral cable, which is unfortunately much too short. Thus, the mount (suction cup) is repeatedly torn from the disc or dashboard or .... Here you could better use a straight cable. I'm beige addressed to the 1st drive and have the cable greatly stretched, then fixed and several days until the desired length achieved so left. Here everyone should try out how long the cable is required.
Otherwise, for the price a great product and a strong buy recommendation!
