Title: Wheels do not fit in
Review: the whole design of the product is acceptable. Cheap materials, but that is ok. However, the 4 wheels under the poles actually could not fit into the holes of the poles. The holes have 2 levels. When I put the wheels into the holes, it only fit into the first level. The wheels were not completely buried into the poles, so the wheels kept falling off. I so used the hammer to tap the wheels into holes. The wheels seems get further inside the holes but they broke the plastic covers of the holes. With the plastic broken, the poles were not strong enough to hold the wheels. So the wheels collapse. So I actually cannot use the wheels.
Is this product review negative?
