Ok bought it.
Justified the cost by suggesting that my 4-year-old could look at other things like leaves and dead insects using it. If the posted pictures of the styli above are anything to go by, this little device will have many more uses than just inspecting stylus tips.
You'll be very pleased with your purchase Mike
Check earlier in the thread for tips on taking pics. It takes a little practice and patience.
If your looking at dead insects prepare for a shock
They look seriously scary. I found a dead crane fly. It looked like something out of the Alien films.
