Something cheap workmanship and value for money is not so special

For my RaceRoom seat I have ordered these holders and actually went on the assumption that this is also a high quality finish. Approximately 50 for two pieces to pay in my opinion is a bit outrageous. Properly stable, this construction is not in spite of the material.

First the positives:
+ The holder can be swiveled and can accommodate a keyboard (possibly plus mouse for the keyboard but must be in mini format)
+ They also do other things except the keyboard and mouse take (z. B. gamepads, headsets, Sweet)
+ Easy to mount (+ does the job (something directly next to the seat to operate)
+ Swiveling in all directions

For negatives:
- Really stable the whole looks not out and it's not. I'm afraid that the partial collapses under heavy load / bend
- In spite of correct setting the holder has some slightly more "play" than required, resulting in that the holder can swivel easily.
- Price is out of proportion to the circumference (sorry, but since you can already almost something myself tinker what is at least as good)

3/5 stars

2 star deduction as bad workmanship, price very expensive
