Wolf Eye Cree Drop-In Problem

I recently purchased a Wolf Eye D26 4-mode Cree drop-in. Installed in a C2, with a Z48 clicky. This has become my go-to light, and in general I'm quite happy with it.

The drop-in, however, has an intermittent failure to switch mode. It will switch modes most of the time, but about one time in five it will fail to switch mode on a soft-click and remain in "100%" mode. Last night I had a run of about 25 attempts in a row, all of which failed to switch mode. There is nothing different on the timing of the failed attempts versus the successful attempts.

I have emailed PTS for support, but haven't heard back from them yet.

Is anyone else having a problem like this? Did I just get a bad one that needs replacement, or is this a common failure?

Thanks.

I've been procrastinating, but intending to start a similar thread. I have not emailed PTS or anything, and really am not looking for additional hassles right now.
My D26 3.7-6V 4 mode has been getting stuck in a mode. It can be any mode. Sometimes it won't light up on the first push. Rarely it will skip a mode. Most of the time it works fine.
That isn't good enough, IMO.
