Fake construction. It should be sturdy for that much money, this requires a lot of attention. To change the background you sweat. The clips are for throwing away and it does not have specifications for supporting the paper, you need to improvise.

Big, for big objects, easy to assemble, I would like more intensity, but it doesn't bother me.

Be careful what you order. Different boxes are available with the same code. While the product photo shows 3 backgrounds and indeed some stores only show black, white, and salmon, in some other stores it is available with 6! The well-known Chinese inconsistencies.
Furthermore, do not rely on the funny tripod included in the package, it is for throwing away. Also, the backgrounds arrived damaged in their center (they are pressed in the packaging by the power supply) resulting in some marks appearing in the photos.
Update: Replacement was made by the selling company. Everything is fine.

Quite useful accessory. The only thing I have to mention is that in the photo, the tripod is misleading and appears much larger than it actually is in reality.

Good product, but the lighting is low. It creates some shadows. It should also have a green background.
