To the extent that negative criticism.
Positives: attached to the windshield with suction cup keeps the mount bombproof. There is no vibration and the mobile phone (HTC) is securely and firmly. The often mentioned here (too) slow opening of the bracket I can not confirm - but is probably a question of patience. I can take out my cell phone within 2 seconds - enough for me!
Conclusion: Would I buy again.
