Seems like the theme is if it ain’t GRS or Lindsay it ain’t no use. Well ..... what about the PULSEGRAVER ....... I have all three and I like it better than the other 2. All 3 are quality. My point is that just because it isn’t GRS or Lindsay doesn’t mean it isn’t quality. It also doesn’t mean it is quality too. I am only an occasional amateur and not a professional So my experience is limited.
