Due to the negative reviews when it comes to glue I again stuck to the adhesive layer four Tesa-Power Strip in the corners and it now holds for a week now wonderfully hidden upside down under the table top. Otherwise, cable ties are also included and the box has cutouts for.
Processing affects not particularly noble, a design prize is not winning the holder. After all was at an air gap between the holder and Fire TV (which can be partly hot arg) thought.
For the price (10,99 with me) certainly completely ok. Only those who are planning to often remove the Fire from TV, should for something else.
