Works well but needs an upgrade
the overall product and idea is very good. You can hang your TV and soundbar to the wall attached to each other and move it to any direction horizontally. I was thrilled to find out this product and willing to pay the extra money for convenience and also quality. But then:
- The box was damaged beyond recognition. While the product was not damaged, I normally save all the boxes and this time I could not.
- you have to buy the wall screws separately, It would be nice to include 10 screws. Also the screw holes are very large so I had to used a washer, Otherwise all IKEA type of screws you have at home can slip and not reliable
- The TV mounting screws that came with the product were useless. all new Samsung TV`s require around M8 1.25 30-40mm screws. this unit comes with 12mm so I had to run to homedepot to get some.
- New Samsung TVs have a curve at the back. the mount is flat so the TV is wobbly and tilted a bit upwards. I had to use extra large washers to compensate that and requires time and work to adjust.still a bit tilted.
- the bottom part that holds the soundbar are attached with 2 bolts, you are supposed to adjust the soundbar with a thin tool after you mount everything. The problem is the bolts are not good quality, they wore off while mounting so as the tool so it doesn't work. Now my soundbar right side is ahead of left part and it will take a lot of effort to fix it. (disassemble all lower part, buy new bolts that match etc...)

These are the problems you can run into when installing. I am still happy with the result and will use it but Bose should upgrade their product to match the newer TV requirements and make the soundbar position adjustment differently.
It would be nice to have a small place for apple TV or similar, I had use Velcro which works well.

Also on the bright side, I could hide all cables behind and my bedroom looks nice.
Thank you for reading.

Very happy with overall quality, very smooth when moving tv around various angles. Disappointed with no wall studs provided, bit pricey, and instructions were frustrating (hard to tell what was right side up since not labeled).
