Even I like HDS so much, just number 2 after McGizmo, I still think we don't need to put HDS in some shrine to kotou everyday and are afraid of saying anything negative. Nobody is perfect except God/Budda/Chairman Mao/King Jong-un
The donuts in Nichia 219 head of last year batch is one example. And now the wear off of coating is another (I remember this was reported before).
American made products surprise me more with their unique design, the creativity, and practical oriented philosophy. As to the details of production and quality control, they may not be on par with Japanese made products, or some of the best mass production Chinese made ones (such as Apple). But here in CPF, most manufactures we care about is actually small workshops. Their products may even have more problems from the quality control, and from not enough test. But again, the creativity, unique innovations, and at the same time the practicality, the robust in the basic functions, the quality of raw materials chosen always amaze me so a lot and call me back to buy more and more USA made flashlights.
