The first one I got buzzed when I played the fourth string and buzzed a little on the other strings.Something was loose on it. Thomann quickly replaced it and this one works fine....guess that's mass-production...AND to Thomman credit there was no fuss.
It's a bit slow to start up but it tunes my guitar . Doesn't feel top-notch quality but then it is half the price of others. If I loose , drop or break it and I had other items from Thomann to buy I'd order another one otherwise the ?15 post wouldn't be worth it.
AS they say ...it does what it says on the tin....there are better but they are dearer too.
Update 3rd June 2015 ,,The rubber strip that fits in the clip has started to come away,,,,seems like the glue used isn't very good. It is managing to hold just now when I press it back on.
It is slow. The read-out is in time with changing of pitch of string if you are turning tuning machine button slowly. Its sensitivity is low ? it indicates shortly. You have to pick string many times while adjusting it until tune-up. If string is far out of tune, it catches any overtone, which is closest to some of tuned notes in guitar mode. But it is OK in chromatic mode. It works better when positioned next to the nut rather on the tip.
