The metal "buttons" that secure the irons in place do not work, resulting in each piece moving and coming off. Unfortunately, because it is also for a baby, I cannot risk using it.

It does its job.
The 3 stars are because it has a heavy metal construction and requires careful installation. If I were to buy again, I would prefer something plastic and lightweight.
Also, if your crib is just big enough, keep in mind that it requires about 10 inches because the screw that supports it protrudes from the crib. Finally, if your crib has bars all around, you won't be able to securely attach it anywhere.

The iron of the mosquito net is of good quality. It is easy to assemble and the installation on the crib is also easy and tightens well. I have bought it 2 months ago and it has not presented any problem.
