Quality is good but the beam profile is like he says, very small hotspot with spill that could be a little brighter.
I have the iTP version.
I use my C7 in C8 format more as I don't have good 14500's and the brightness with 2xAA makes the not so good beam pattern usable.
*add*
The specs on the suppliers site lists 6-190 lumens, this is only true with the 14500 and 2XAA voltages.
On 1.2-1.7v you will get a max of about 110. (compared to other AA lights like my LD10 in ceiling bounce)
