Excellent heady duty built monitor mount

Excellent heavy duty built quality ultrawide monitor mount. I have mounted a 49 inch ultrawide lg monitor and it holds it well with no issues. Adjusting the tension was quite easy and the assembly of the product is quite straight forward. I will highly recommend to get a this product if you own any ultrawide monitor. It hides the cable (monitor power wire and hdmi cable) really well to give a clean looks. Also ultrarm do sell monitor arm only if you want to add additional wide monitor. So far im very happy with this product.

Heavy duty arm...

This arm is extremely well made, is heavy duty and has weight to it. It holds my monitor with ease and it allows me to clear it off my desk by swinging, lifting and/or tilting my monitor into multiple positions. It easily attaches to my desk or table in just minutes and am really happy with this item.

Absolutely amazing monitor arm!!

I have a 34 inch curved monitor and it's white and this arm looks absolutely amazing. Not to mention the quality of this is way beyond my expectations. It was easy to put together an attach my monitor to it. I did have my daughter help me just because I was worried that I would make a mistake or drop it! My monitors were to expensive so I had to make sure to get a monitor arm I can trust for a monitor. I 1000% recommend this product. I'm will be getting three more because I have (4) 34 in curved monitors. I work from home so I've got 2 curved monitors for my workstation and I've got 2 curved monitors for my personal computer. I've been working for home for over a decade. This is exactly what I needed. Absolutely thrilled with this product not to mention an incredibly fast shipping! Amazing product and a really great seller!!
