Gravity Headphones Holder f. Desk

I bought this for my 5 cm thick table but this product clamp opens only 4.5cm, which is not mentioned and even misleading info mentioned as 10 cm depth thinking this was usable for tables up to 10 cm just like their monitor stands with clamps as they advertise and even put a video here mentioning they can fit upto 10cm thick tables and I thought since this is also same company, they would not sell thin clamp opening products double the price of others. I especially looked for the clamp size info before I buy this product but apparently they have NOT displayed this info but 10 cm depth was displayed which is misleading. How can you sell a product without the most useful info of the product?? If your table thickness is more than 4 cm do not waste your money on this product!
