So meticulously manufactured and packaged! It was a pleasure to install it and imagine people who use it find comfort in the firm grip. Pic. 1, weight = 581gr; must be some solid material inside; Pic. 2, I would suggest fixing the bottom screws first then the other screws; Pic.3, I notice no-glow from the rings, perhaps the glow would come later. ⭐⭐⭐⭐⭐ Thank you Seller for such a marvelous Product. I donot mind at all to recommend you to people who ask once they find the handle.
