Brad,
In my experience the Segway isn't as consistent as the Reticle-Tru, for a couple of reasons--primarily that small bubble-levels aren't always all that accurate. But the Segway beats some of the other gadgets on the market, which depend on a couple of bubble levels placed on parts of the rifle and scope that aren't always "square" themselves.

Hi John, I hear you on small bubble levels, but my Segway is an ancient model and lacks a bubble level. Really, I find a bubble level completely unnecessary anyway - if the reticle is leveled square to the scope base, that's all I really care about.
