This was exactly what I wanted. It is not obtrusive if you were hoping to let the rest of the room, furniture, and curtains speak for the setup you have going on. Alternatively, if you are going for a utilitarian/minimalism style (which I think I borrow from for my room) this also works very well.
In terms of putting the thing together... I will say, it was not the easiest time ever. The instructions were not bad, if a bit sparse. You'll have to truly think things through a bit before getting going. And it definitely is simpler to set up with two people - in fact, the instructions that they provide basically require two people to put this thing together! However, I ended up switching up the instructions a little bit to figure out how to install this on my own. My modified instructions: (1) measure everything properly. Twice, three times, four times, as many times as necessary to make sure you're comfortable; (2) put the centre piece in first (if yours comes with a centre piece... if not, ignore this step); (3) Drill in one end piece [for myself, I'm going to say this is the left piece, as that's how I did it, (4) bunch your curtains on the left side together, insert the bar through the middle piece, going all the way to the left side, (5) screw the left end of the bar into the end piece that you had drilled into the wall in step 3... (6) put the other curtain on the right side of the centre piece, (7) screw the right end piece into the end of the bar on the right side, (8) drill the right end piece into the wall.
Easy peasy. Sort of. I did a lot of sweating that day and measuring and remeasuring.
So my advice? Do this with someone else. But if you can't find someone to do it with you, know that it's possible to put this together on your own, but you might just have to modify the instructions provided by the booklet a little bit.
One tiny note of annoyance that I do happen to have is that the curtains do get stuck on the rod at the spot where the smaller rod piece fits into the larger rod piece. To get the rod to stretch out, it's two pieces where the smaller piece telescopes into the larger piece. And so the grommet on my curtains get stuck on the transition at times, and it's a minor annoyance and inconvenience. But like I said, minor.
Also, a minor manufacturing blip. One of the end pieces, I thought I was going to have to drill a hole for the screw. However, it turns out that the hole had already been drilled, it just wasn't punched correctly. So before returning the thing because the hole wasn't drilled properly, try doing a low speed drill of the indentation and see if it was just a small piece of plastic that wasn't punched through correctly.
The expansion anchors that are provided if you happen to be drilling into somewhere without a stud works quite well. Likewise, the screws do just fine if you are drilling into a stud. I was lucky enough to have to accommodate both non-stud areas of drilling as well as studded areas. Lucky me, I got to use all the different components provided. But just so you know, no worries there. The expansion anchors work fine, just be reasonable and go slow with the hammer so you don't split it.
