Yea not sure whats going on, I have tested it myself and it works for me so I'll try and get in contact with the people who manage the survey website, thanks again for trying though.You're bringing up some great points that are exactly what I need to talk about in my report, especially as I'm looking at the 'viability' of these machines.The fact that you have tried three different machines and struggled to use them easily is great information for me and is an important point I can bring up in my report.What I am finding ineresting is that different scientific journal articles that I have found are bringing back mixed results for how the recycling of the plastic effects its strength, some saying strength immediatly decreases after one recylcing cycle, and others saying strength is actually maximised between 3-5 cycles and then begins to decrease. Thanks again
