This perks for using this stand is that it can be disassembled to take up less space in storage, and it is cheaper than a one-piece stand.
The cons is that the pole doesn't seem to want to stay tightly screwed into the base. Over time in a lab, it starts to get looser and the bolt has to be tightened. Slightly annoying, but you can make due with it.
The other thing I noticed is that the pole seems to be slightly narrower than other ring stands I've used in the past (used to teach HS chemistry.) This means that a standard-sized ring or burette clamp does not attached really securely to the pole of this ring stand. The pole is not centered inside of the clamp/ring attached and it makes it very difficult to screw that item tightly to the pole. The ramifications of that should be obvious.
I've made due with this ring stand in an introductory physical science class, but we didn't use it in any set-up where we were heating. I would not use it in that case, as it is far too wobbly. Perhaps the single-piece ring stand sold here would be more reliable.
good support for experiments
Review by Tammy
This stand has been very useful for our physics experiments. While it cannot support a lot of weight without tipping, it gets the job done and is easy to use and store.
lightweigth but sturdy
Review by Melody
This ring stand is perfect for most Chemistry experiments that require a support of some kind. Another good product - processed and shipped quickly!
