### ⭐⭐⭐⭐⭐ Best arm
*by C***U on August 18, 2026*

Best arm ever ..it even didn't move ¼

### ⭐⭐⭐⭐⭐ Shipped with missing components
*by V***N on July 20, 2026*

*UPDATE* The team got back to me and sent me the missing piece at no cost. I ordered the extension arm to add another monitor to my already existing Ultraarm base monitor mount. I was excited to receive it in pretty timely manner but was bummed to see that my monitor arm shipped missing two crucial pieces. I checked a million times over through the packaging to make sure I wasn’t going crazy but with no success. Ultraarm provides a piece of paper with their support email insisting you reach out to them if any parts are missing so I did that as I was really pumped to get the rest of my package so I could mount my monitor. Unfortunately days later and a follow up email from me later I’ve still heard nothing back from them. I guess I’ll probably just have to do a full return and hope my next one ships with everything it’s supposed to.
