I had been using the standard 3 leg mic stands which were you cheaper type - the Millenium is a very significant upgrade, great quality plastic, sturdy construction and tighter tolerances, I mainly use a mic stand to just throw a 57 on it and latch my talkbox tube to that then wrap it around the main joint and leave it set up in the house.
The base is heavy enough to support a 57 or 58 at 90 degrees and half extension but a good knock will still bring it down so I'd only recommend using it like that in very tight spaces - the second one I bought is between a wall and a piano in the house as my partner sings and plays and that's how we use it in that specific space and is unlikely to get knocked over.
The height adjustment is very quick - just grip, set and let go.
All the fittings are solid and I think I've only had slippage once which I think was user error, with the tolerances being so good wherever you tighten it down, it doesn't slip over time like cheaper stands do with weight on the end.
Overall worth the investment if you have been using a stand half the price for years and looking for a very significant and reliable upgrade.
