Great after 18 months
I have an MTC P7 and it's going great after 18 months. Very happy with it. I don't need 8 modes but the intermittent strobe setting (3 fast flashes then pause) is good for daylight use. It's an ideal light for daytime use. You get noticed and I feel safer.
I did have to dismantle and re-seat the contact in the cap -- it was OK after that.
