Hi all,
Found and bought this a couple months ago. Was the cheapest I could find for any dual screen table mount. Arrived in a few days after purchase, so I was very excited.
Works very well and much sturdier than I originally thought. You really need to ensure the hex head bolts are in properly otherwise it may seem flimsy and droop over time. The Allen key supplied appeared to strip the hex bolt but after changing the key, it was fine. Since solving this, it has not sagged or had any problems. Until posting, I had no idea I could change the vertical height (which annoyed me).
I really don't get why websites like these need to hold account details… this is really putting me off at the moment.
