I've had a NS53A (one of the NSX3 lights) for a few months now and thought I'd write a review on it. https://davestechreviews.wordpress.com/2020/05/24/nightwatch-nsx3-ns53a-version-flashlight-review/ It's my first proper review, so any feedback or questions about the light are welcome.
Thanks for your detailed and valuable review. I ordered four of these a few months ago, received one promptly and my supplier told me that there are no more in the pipeline. I am glad I got one of these red hot little screamers, and I absolutely love it!
