I use it Tim but not to it's potential if I am honest. It is a great piece of kit to prove compliance and the model it suits us down to the ground as we use a 50/50 split between cuplok and tube. I would recommend it but for the smaller operator it can be tough getting in to the office to play around with it. I have around 3 updates still to load on to my dongle, it's a long story but I have a spare at the moment and I have had it that long I'm not sure what's what any more so a couple of things may have changed but the only thing I didn't like or maybe just didn't fully understand was the chimney. I haven't got the Draw It but would invest again if I thought I could get in to the office to use it.
