Not as good as https://www.ozbargain.com.au/node/666948
Maybe VIVO has better build quality than Suptek?
I'd get this if didn't get above Suptek Quad.
I use this arm mainly for standing when working.
It can not be easily lower down (comparing to https://www.ozbargain.com.au/node/665950), but suits me as I don't sit when WFH.
Some people use this to setup broadcast desk.
