I have used local Chinese tuner which you get in the local guitar shop and never like it as those were not durable.But we all know mobile tuners are not accurate so with a lot of research and reading reviews I finalized to vault tuner and what...It surpassed the expectations the quality is felt at first you take this in had, it is heavier and finely built than other tuners.Only one bad this that it did not came it with battrey, but for such quality, I can compromise that.
