I have been using fvrier 2007 (and I still stacks orgine) Ragit it fast enough, although I had some surprise when I dive the bridges of the guitar (nothing severe) the ratio quality price is right, I would do this choice trs happy because this little tuner and trs simple to use cheap it fits in your pocket (for those who are afraid of losing, we can hang a strap) is the tool IDAL short for those who want something simple, cheap, good and compact
