This screen is potentially very good, or useless depending on who you are, the room you are recording in, and what you hope to do.
In my case, I have a room with a bit of sound absorption on the walls, but not fully covered, no bass traps yet. It's still a fairly reflective environment. I found the screen helped significantly in reducing reflections in the recordings - especially when singing or shouting. Additionally, I think you can easily cover up either the top of bottom with a towel/cloth depending on how you have your mic and pop filter set up.
I reckon that there could be environments where this simply does not offer enough absorption.
I put the screen on a mic stand in the middle of my studio. The screen is quite bulky, but easily transportable if you have a car. It isn't heavy.
To conclude, this was a good solution for me that helps me get much better, albeit not perfect results. It is a significant improvement, though, and I am happy with my purchase. In my case, I think it was well worth the money.
Take time study how reflections and treating your room works. It is knowledge that will benefit you for the rest of your time with music and help you to make an informed purchase.
