I bought an Inova X1 as a backup to my main bush light because they both run on AA batteries. The Inova has been a good light but I cannot compare it to the others mentioned because I have never tried them.

Two negatives to the Inova X1 I have found is that the metal case can be cold in your hand and being metal it is not easy to hold in your teeth when you need to have both hands free.

Otherwise I have had no trouble with it.

Take care,

Mike
