Pop up Xmas trees. Good idea, or naff?

[Wineorcider]

We need a tree to replace one from the last few years.

Went to Argos today, but no pop up trees on display. Are they any good? How do they look/work, for want of a daft question?

Just to see if they might be what we're looking for (small house).

Anyone able to help?

We have a white pop up tree got it from b&q a couple of years back get it out of the box and pop there it is !!
