This is a good alternative to buying the whole adjustable standing desk. I did read previous reviews where they said this was heavy but understood only when I saw it at home. Since the new desk (Clifton desk with hutch by Gracie oaks) was not very big or super sturdy, I assumed that it might have been a wrong decision to get a heavier one. But, it works great. It fits the desk perfectly. I put one star less because, I found the buttons a little hard to press to adjust the position but maybe with constant use it might get easier to manage.
