The less (for improvement):
1. To start, the most important point is to know that this system must absolutely be mounted on a solid wall and not on a single partition. Or, it will install decks on both sides of the wall to the TV does not tear the wall (my TV is a Samsung LED TV 41 "). Fortunately, many fasteners are provided as appropriate and adaptable outdoor walls .
2. The price is still quite high compared to what there is on the market. It seems to me that this is the most expensive. I think this type of product should be sold 150 euros, not more.
3. The cable passes is relatively simple but precisely not worked enough. The cables on the second arm (closest to the TV) is still apparent. For example, from Bose, connectors go fully in the stems and are covered by a flexible plastic clipped.
4. The first part of the arm is very rigid and should be handled carefully all with both hands to avoid potential shocks on TV against the wall, for example.
