What is wrong with conduit

[Delta]

Is it just me or are you guys also battling to bend 25mm pvc conduit?

I know how to bend and it's not my spring bender.

As soon as you apply a bit of pressure it just kinks terribly and closes the bend.
This was a bundle of "Nur" conduit.
Terrible stuff.

What is a reliable make of good quality of conduit that can actually be bent?

I'm busy with a 450m square house only using 25mm pipe and can't battle with sh!t conduit.
