I used it when arranging a lightweight desk with a height of 700 mm next to the desk of the old JIS height 740 mm. I am satisfied because the height is perfectly fit. I have installed two monitor arms and three monitors, but for now there is no problem. I will buy this if it is necessary for the same purpose.
Because most of the hexagonal struts sold at nearby stores are small objects for electronic boards, there are many sizes and it is saved. The price is affordable and things are good. I think that it would be nice to have a cheap delivery method such as e-mail facilities when purchasing a small amount.
