Amazon Customer 5 the installation was quite smooth even if it needs to be assemble each piece by piece, still very intuitive and fast. on the table legs to pretty easy. They move around smoothly and are easy to engage and disengage . probably the only little complain is that they stick out about 15 cm from the legs even when disengage so you have to be aware of them for not to stumble in which can be quite painful as are just piece of metal. I don't have to go around my table so in not a big problem usually but when I move it in the room center then I have to keep in mind.beside this they are a excellent product. very happy about it.
