Very disappointed Wendy, mines the same tears the paper and it a FAFF to try and get it straight. The join when it opens out is not flat and its right where you need to measure for a A5 card. 
This is not fit for purpose, does anyone know if  Joanna do returns???? Had the envelope punch in my basket has well and changed my mind at the last minute. I already have 2Crafter Companion, a Martha Stewart and a Helix, so glad I didn't order that too. Gill x
