Review on 🚴 Enhance Your Riding Experience with Rox Speed FX 2in. Pivoting Handlebar Riser for 1 1/8in. Handlebars by Greg Quinit

They are well made, the finish is great. Gave 4 stars because: 1- The hinge is separate so it's difficult to adjust properly. 2- Instructions are not provided. Of course, they speak for themselves, but some less mechanically oriented buyers may benefit in some way. 3- quality screws are not supplied. BMW has torx screws everywhere. Why Allen Screws? The screws also protrude from the underside. So their Mark II could probably solve those problems. No indication is given as to the cause of the thread cut on the underside. I assume this will be a way to connect them so they rotate together, but again no instructions or details are provided.
