Back to the Product I recently had a customer bring one in and I was a little surprised at 2 aspects.
1. The spherical ball in the flex joint looked like it was straight off the lathe. It was quite a rough finish and certainly not chromed or polished.
2. The arms themselves are mild steel seemed pipe - basically water pipe and only about 5mm wall. On the long arms it's even bent making it weaker again.
The spherical ball being poorly finished will result in accelerated wear and of the maybe 10 brands of arms with "flex" joints this is the first I have seen this.
Also those arms have used the MUCH stronger DOM, Chromoly or other quality steel in the arms themselves. And usually at least as thick if not more.
Reason I mention this is because it's the sort of thing a lot of people won't notice at first glance.
