I bought two of these elevators to replace 2 other "simple" ones (which were installed by the carpenter who made the closets) that broke due to weight.

I bought these specific ones because even though they are quite expensive, they are the only ones with a rating of 20 kilograms, which is not difficult to reach with winter clothes (coats, etc.). It remains to be seen in practice, of course, but in any case, a product with a rating of 20 kilograms will likely withstand much more than another one with a rating of 12, so I considered that the purchase was worth it compared to constantly buying and replacing cheaper ones.

As for construction, they seem quite sturdy and their bases appear to be much more durable than the thin plastic ones that the old ones had. The only thing I don't like is that the support of the base is done unilaterally (a vertical line of screws on one side of the base) and therefore the weight "pulls" the screws towards one side instead of "sitting" on them. But even so, with 6 screws on each side, I hope they will withstand.
