I just don't think the speed disadvantage was worth losing a star, since the intonation ability here is incredible

It loses a star because I have not been able to find a convenient place to hook this thing to my guitar while not in use.

But stars are meaningless

The Fender is plastic and it works fine on my electrics but not as well as on my acoustic.

The Shubb will not get in the way of your hand and is, as they say, fully adjustable in tension

It works exactly as it is supposed to, with just the right amount of pressure on the strings.
