I do.
105 liters.
Not sure what you are asking. The smaller ones are quite useless IMO. Unless you only want to keep livebearers or betta you should get a 60 liter one. The life range is not great as the floor space is midget. I find my filter is adequate.
I like them.
Pros:
They look cool IMO.
They're made of sturdy acrylic.
Cons:
They can make fish look bigger than they are.
Small surface area.
Filter is weak.
Cannot stock like regular tank.
People on TFF will hate you for owning one XD.
Lighting is tiny.
Not much flow.
Bad for growing plants.
Very expensive
Cleaning is kinda tough.
Under gravel filter with sharp rocks means bottome feeders should be minimal.
All in all, I got my biorb cos I was sick Of my glass tanks shattering and wanted a neat all in one acrylic aquarium package. It has served me well. For my purposes the filter has gone well. I have live plants mostly swords crypts and anubias. I do not like the small ones or the life or the box type ones. The ones you want are the 60-105 liter bowls IMHO.
It is far easier to get second hand- I got mine at a great price online in a rare deal on gumtree.
I would reccomend biorb for tetras, livebearers, cherry barbs, rasboras, some abantoids and inverts.
Hope this helped.

You can add an internal filter, but it's difficult to get it to sit securely and doesn't look that good. The included filter system is very poor.
I actually looked at the BiOrb range when I was looking at getting a nano set up last year but decided against them, even though I do like the 'bowl' look.
For a start, once they're full of water, they distort the fish horribly.
i would say they're another gimmick and more for home decor than 'proper' fishkeeping.
shame...they are really beautiful. maybe as an over planted nano tank...but now im rethinking a larger one. would one even be able to change the bulbs from the light fixture..my thought was it would look super neat as a glo fish tank,but once again fliteration becomes an issue. and
Danios do not have the room required for them in a biorb sadly. Yu can change the light I have not got round to it yet.
