## Customer Reviews

### ⭐⭐⭐⭐⭐ Exactly what is needed
*by K***R on July 17, 2025*

I got this for my 57" Super Wide screen monitor. Works totally as needed. Sturdy all around. I also got it with the extra arm so I could put another monitor above my main super wide monitor. Easy and flexible to setup. Very nicely made. Well worth the money. Seems like the arm and tools/screws et al provided are all decent quality and thoughtfully combined into a comprehensive package. VESA screws and tools for install all provided. Great product.
