I bought Wizard Pro again in 2019 hoping to have more luck and this time everything is fine, it has excellent performance, I don't know if the first sample was a lemon or if in the meantime the led has become XHP.50.2 (or both) the new one Wizard Pro is very powerful and works well but has not been used so far
enough to make a judgment on durability and reliability.
Maybe I shouldn't have talked ..
Some time ago I saw that my Wizard Pro was not working on Turbo 2 and extracted the battery I measured 3.20V I did not remember having used the Headlamp.
I have now verified that the Wizard Pro has a strong parasitic discharge :-(
I had the suspicion but not the certainty, then I did an only 8-day test and the battery (Samsung 30Q) dropped from 4.20V to 3.93V
Now I will do the test with the original battery but I fear that the problem remains.
I am also in doubt as to whether to return it under warranty for fear that the replacement one may have other problems.
