On first glance, these speakers stands are excellent. They feel weightier than most of their similarly priced competitors.
First use, I found them to be extremely sturdy, and I had almost no wobbling once I put my speaker on top (RCF422). I expect they could even take more weight without much trouble.
Unfortunately, the screws, connectors, fixtures, are of the quality you would expect at this price range. So, after some medium to heavy traffic, they have broken. I can still use them....just.....but it won't be long before they go to the hi-fi store in the sky.
Buy these for light use, or if they are installed in one location. They are good stands.
But, if you gig two or three times a week, and are continually putting up, and taking down, expect them to be knackered within 6 months or so.
The carry bag that they come with again, is adequate, but the zip soon broke, and the material ripped after a few months.
