Invision Single Monitor Arm Desk Mount for 19 to 32 Inch Screens £26.75 with voucher Sold by Invision Technology & Fulfilled by Amazon

Just binned one of these, lasted about 2 years. The weakness is the thread on the bolt - it's really soft and has no thread after screwing/unscrewing a dozen or so times. I'd only recommend if you are positioning it permanently. (edited)

I've had the previous model of this arm (different cable management) for 4 years now. Brilliant quality, never had an issue and from what I've heard, invisions CS is second to none. (edited)

Excellent bit of kit.

I can confirm this had the 10% discount voucher on for a short time earlier today, but looks like they've since removed it.

There is no 10% voucher anymore.

Have two of these, work great. Looks like this has new cable management which is a bonus as the old one was a bit tight if running more than two cables

Had about 15? of these and the dual arms through work over the last 5-10 years, they generally work well but had 3? duff ones where the screen wouldn't retain the correct height.
The tightening mechanism for this part is particularly finicky where you need to tighten it nearly the whole way to one side, and then there's extremely fractional tightens to correct the movement.

I got so frustrated that I've stopped buying these and instead look to monitors with height adjustable stands like this one:
amazon.co.uk/Ben…LD6

Failing that I'm trying other monitor arm brands that are a bit cheaper to see if i can avoid these issues.

I used to recommend these highly and most people would probably still be happy.
Their Customer Service is usually good, but at some point it just gets annoying to faff around.
For reference, the last time they referred me to Amazon Customer Service instead of dealing with them directly (edited)

I would bite at £26 but 10% isn't available now
