In an age of hundreds of these type of products available to us at a fraction of the price of this one I can only say that it is way superior to any of its competion that I have come across.
After over a year of constant use in my studio it has been nothing but reliable and robust, constantly being man handled and moved about. It is sturdy, has a good weight and balance and withstands heavy use.
I have had several other products over the years that have not survived 3 months but the K&M 19800 far surpasses them in construction and reliability. It comfortably fits my 10.1 inch tablets with a their sleeve protection on and certainly any mobile phone,though I would consider this an extremme mobile phone stand and more suitable for tablets.
In conclusion, if you want a quality, sturdy, long lasting tablet desk stand? Look no further you are on the right page.
