good would be better!

... Not mature.
am dissatisfied and do not find anything good in the part.
for 500mm schänkellänge is:
1. This locking device is simply too stiff.
2. schänkelstärke of 1mm is too low, and thus unstable.
3. the schänkel turn itself from the dead weight. how can you can use it to work properly?
the manufacturer should be concerned because times.
and another thing. never direct sunlight or extreme heat expose the liquid crystal display can not tolerate that.
but that's quite clear.
