To be honest, I am only moderately satisfied with this underquilt, mainly because of the drawstrings and mounting cords. The drawstrings are very weak (not to say - flimsy) and slip off, which loosens the underquilt. The cords themselves also seem to be of average quality and are sewn in directly - probably after some time this will be a part that will need to be modified on your own. I also miss some convenient system to lock the underquilt on the sides of the hammock - it tends to move, although I managed to solve this by passing the side tensioners through the loops that I have on the sides of the hammock. The set also lacks carabiners, so depending on the method of hanging the hammock, separately purchased ones (e.g. small S-biners) may come in handy. Additionally, my scale shows 990g when weighing the underquilt in the cover, so I don't know where the 810g declared by the manufacturer comes from. I regret that I didn't test it out right after ordering - I would have returned the product. PS I am very satisfied with the Ważka hammock from the same manufacturer, which makes my disappointment with the underquilt even bigger.
