I bought these based on the price. The material is pressboard, with a black textured finish. I didn't expect top notch quality - but these certainly don't look like $50 stands to me (they look better than that).
Other reviews complained about the screws splitting the wood - I don't see how that is possible, since the legs are pre-drilled. Either the holes didn't exist, or the stand was assembled wrong. I suggest starting all four screws (on either the top or the bottom) in the holes, and then tightening from there.
In addition, I couldn't find the length I wanted, so I compromised with this one. I wanted a 28" - which isn't made. Now that I've seen one in person, I wish I would have bought the 31" - because I see that I could have chopped off each leg three inches, replicated the pre-drilled holes, sprayed the newly exposed wood with black spray paint, and had the 28" height I wanted. So - if you want a custom length, and are a little handy - buy a taller set.
Another review indicated that the screws are not recessed - but they are. As received, holes are countersunk on one side only - so that the screws will be recessed. If you put the stand together wrong, yes the screws will not be recessed.
Pros: Price and finish quality. They may be the cheapest stands you can buy, but they don't look it.
Cons: The speaker base hole is small - and the speaker base pads are thin. Go to a lumber or hardware store and buy cabinet door/drawer bumpers - they are thicker. As received, the pad thickness limits cable size quite a bit, but the fix is easy and cheap. Still well worth the money. If you're using 16/18 gauge wire, you'll be fine as is.
