Something is not right with the reviews. This particular leg is trash... and I paid 5 euros for each one. What I imagine is that there are different qualities in the same design. Be careful... buy one first and if it works for you, then order more.

Excellent appearance, very good price!! Sturdy, placed on a sofa to raise it a bit... Time will tell..., (The dimension of 12cm height is missing!!)

very strong and durable... I have installed them for a year in closets and cabinets... really wonderful

Cheap, materials are a bit mediocre but it got the job done!
Bought it for a coffee table. Satisfied with the height

Convenient to install on wood, melamine, and even though it looks like plastic, it seems reinforced. I can't know if it can hold very heavy weights, like a wardrobe or a bookshelf, especially if it slides on the side and encounters an obstacle and gets stuck. Maybe the taller ones are more sensitive. Overall, it seems durable and the finish is very good, I just mention it for someone to keep in mind. I think that with a little caution in moving very heavy constructions, there shouldn't be a problem. For light constructions, like TV furniture, etc., it is definitely more than okay.
