I bought it in haste which I now regret, I find it clunky and un-responsive, the tools are not very intuitive the whole interface is complicated for a tool that should be basic & simple to use.
I do keep going back to it for another go thinking that if I try again I will get the hang of it, and am only doing so because I feel I should because I paid $130 for it.
I have not had the confidence to use it outside the office, I would rather take the laptop.
I would be very interested to hear another opinion.
I have since bought Redstick site cad which I have found quick easy to use straight away - $15!
