MusicNomad MN602 Precision String Height Gauge

I've been using a cheap version of this tool for years, which I bought from Amazon for about £5, thinking "it does the same job" ... Heads up to anyone reading this, IT DOESN'T!!!
I bought this one because they claim it's easy to read due the clear writing on the black background, and I was struggling to see the measurement lines on the old steal one. I can now confirm that their claim is true.
What has also come to light is that the measurements on the cheap one were all over the show. This one is precision accurate. With this one, I set the heights by the gauge and it plays perfectly, no extra adjustments by feel required. Wish I had just spent the extra on this one in the first place and saved myself a lot of time and eye strain!!
