first of all, the package didn’t contain the AC converter and the screws needed to fix the sign. But the worst part is the work wasn’t done accordingly to the project. it was arranged that the wires should’ve come out of the armbar side but they have been instead placed where the holding plaque is meant to be fixed. how can the wires be connected to anything? how can you fix it to the wall without breaking the wires???? I had to put spacers to create space for the wires to come out. then the worst part comes: i needed a 50cm long armbar (which ofc is quite a long bar so needs to be strong enough to hold such a big sign) and they told me that they had done the tests w engineering team to make sure the arm was resistant and i said great! Now Look at the plaque that is meant to HOLD all of that counter weight on a miserable 3mm thick metal plaque welded so poorly you can see 10 welding points in the picture. this has been the most terrible experience ive had on alibaba. 500$ in the trash
