I give it five stars because it is well-built and has easy assembly. However, the quality control of the product needs a bit of attention. Three holes were closed, and I had to open them with a hammer (not difficult, but not pleasant). Also, in the design, for similar assembly points, the washers are fewer than the connections. Both observations concern the manufacturing factory and not the company that does the resale. It would be good for them to convey the concerns.
