Have used this product numerous times for my projects over the last two years and never had a problem; in fact would highly rate it as an excellent product priced rather more realistically than the prices you see in the high street stores.
Unfortunately the most recent batch is dreadful. It's quite clearly been replaced by an inferior quality paper; the labelled ("print on the other side") printing band has disappeared and has been replaced with a plain white band (not helpful!) and, where it was previously on the non-printing side, it is now on the printing side of the paper, reducing the printing space available. Not great when you run a large batch through the printer before you realise this and lose a centimetre of text/imagery on every page! Secondly, the ink comes out a little more faded than than that of the previous packs I've had and, lastly, it is far more sticky (with or without ink!) causing multiple pages to run through the printer in one go and create a sticky and haphazard pile on the out-tray.
I will be sourcing another brand from elsewhere in the future.
