IKEA aluminium curtain tracks - any good?

[Thesunrising]

Just that really. Desperately need to get curtains hung this weekend and need silver look- track for three metre wide curtains. Can't find any other shop that has this length in stock and can't wait to order any on the internet. Neither do I want to pay £150+ John Lewis prices.

I need to hang medium weight lined curtains and don't want it to be a bodge or feel cheap. Are the Ikea tracks good? Do they run smoothly? Thanks!

We have them in all 3 bedrooms. Put them in when we moved in 7 years ago and still work fine.
They definitely don't look as expensive as the dunelm ones we have but they look fine.
