If anyone wants to get a feel for what it can do - simply copy a mask - expand it in Photoshop or whatever to the size you want it - print it on A4 - take it to work or Officeworks and transfer it onto a transparency.
The cost to get a working model and play with it is under $3 - if you like it and can see its value - order one. I cut my one from cardboard with a model knife before I thought of the photocopy to transparency route -and it has worked a treat for the last few months.
If you want to have a permanent version you can take out to the field - buy one knowing how effectively it will work!
