+ Although this combination and the cable to be quite heavy (about 1.3 kg), it can be heaving with the arm in any position and remains reliable. Springs and bearings so strong enough for my needs.
+ Can be very good and flexible mount
+ Looks good, but:
- The material quality is unfortunately disappointing. Some built of cheap plastic, barely scratch-resistant paint (yes, paint!), Even chroming has been omitted; merely chromfarbener paint used.
- Long-term use can only be sold at heavy optical loss
