I've had my Wizard Pro for a little while now. So far I like it a lot. It puts out a good spread of light, is very bright, and feels very cave-worthy, in my opinion.
That being said, I've read a few negative experiences from others who have bought this headlamp. Most of the criticism is due to a programming issue some are experiencing that prevents the light from turning on in certain conditions. There is an inconvenient workaround to this issue, but the good news is Armytek is supposedly looking into a resolution which will probably involve a recall of the affected lights.
If you are considering getting a Wizard Pro, I recommend you do, but I would also recommend that you wait a bit for them to work out the programming bug.
