This is an asparagus steamer. Asparagus steamers work like this: you put a thin layer of water in the bottom, heat it up to boiling, then put food you want to steam in the basket, lower it in, put the lid on, and come back in a few minutes
Because the top of the pot is so far from the burner relative to the size of the pot, you really can't efficiently heat water or use this thing like a stockpot or a pasta cooker the way some folks have asked. That's not what it's for, and by that I mean the pan material at the bottom is too thin to effectively transfer enough heat up the sides of the pan before it starts scorching whatever's touching the bottom of it, like stuck on pasta. You would want this pan to be close to twice as wide as it is before it'd be any good for boiling water for pasta or making stock or whatever.
That's a practical reason to get something else if you have any plan on using this for other than steaming veggies.
There's a second issue with this item that you might wish to be aware of: some folks think using aluminum cookware contributes to the risk of Alzheimer's. Short term studies have never demonstrated a link, but short term health studies, by definition, can't prove or disprove such a thing as a long term health risk. No long term longitudinal study has ever been done, mostly because the EPA and FDA do not pay for them because they don't have any money for them. The only people who would pay for it are in the aluminum industry for whom doing so would be lose-lose. By that, I mean the broad public assumption is currently that aluminum cookware is safe for humans to use - so the best the industry can do with a longitudinal study is to show that there is in fact no long term health risks to using aluminum cookware. In other words, they can only break even by proving it's as safe as people were already assuming it was. Any other results, even if they're inconclusive, will be bad news for them and they will have paid to make it happen, so, that's a no for them.
When I looked at the amount of research that HASN'T been done on the long term effects of eating food prepared in aluminum cookware, and compared that to the specific things the industry groups are careful not to say about why they think aluminum is fine... I ended up getting rid of all my aluminum cookware. And I mean, I get it. People sometimes shrug this sort of thing off, they think 'whatever, I'm not getting rid of my cookware, I paid for that shit. And how could aluminum cookware be dangerous to your health? People use it all over the place!' You know, that's how folks think... like they did with subprime mortgages and Oxy Contin. The number of deadly-ass things that we once thought were awesome is enough to stagger the mind. Once upon a time people thought tobacco was not only safe but a bit of a cure-all. Same with cocaine. People used leaded gasoline and Thalidomide and DDT.
And if you think that's bad, understand that people do this stuff with radioactive stuff too. There's a type of ceramic glaze that was very common in midcentury modern stuff that is hot enough to make a geiger counter sing four part harmony. People actually ATE radium tablets, this one dude was famous for selling them and he claimed he felt awesome right up to when he suddenly died. They did an autopsy his body was riddled with tumors and holes in his bones the size of silver dollars. He sure did make money selling radium tablets tho. Seems ridiculous to us, but that's the kind of monkeys we are from time to time.
The truth is, people are bad at detecting long term risks because by definition their lives hopes and dreams take place during the detection period. Life has a way of distracting one's attention so people tend to after a while just look around, see what other people are doing, and figure it must be ok if they're all doing it. And every once in a while, that'll really bite you in the ass.
