Saw this while browsing for a monitor arm a few days ago and keen to getting one after purchasing Dell Monitors last year, specifically the wave of delayed orders from Aug 2020.
The link goes to MDA20, you would need to search for MSA20 on the site or use this link.
PS: I saw a previous post for MDA20 last Feb 2021, and it had negative comments. I agree some monitor arms are better (eg. Ergotron) and cheaper but hey its Dell. If there would be a deal for Ergotron monitor arms please share it on OzBargain.
Anyone know if there's a minimum desk thickness? I ordered like 3 monitor mounts not realising my desktop was too thin (Omnidesk).
