First of all I prsise I have almost never tried other tuner of this kind (eg the boss).
I have the pedals (bought on thomann for 18) for a week.

Assets:
I find it quite prsise, fast (when going from a rope in the other ex, or that turns the lightweight mcanique a rope)
Trs's clear the LEDs, even the pedals 1m80: p I find a good trs.
It looks pretty solid I despite the fact that it is plastic
No sound dterioration losque that the guitar comes in and we resort to the pedals into the amp. It is completely transparent.

Cons:
She eats! I do not know for other pedals (APAR was I just a crybaby, I'm in. trspdale: p) but just leave the jack input branch one night (tuner complexion, but the same happens when the so) to drain the battery Fully ... I think I'll invest in a transformer ...
Previous opinion as I find it sometimes a little difficult to give with the low E prsision guitars but trslger, and the price not the g ing.

Regarding the location of the battery under the cover above the pedals, I do not find that the system is stupid, it's not hard to remove or put a damper on even if t shall have the pedals better ...

In short, for that price, it's a good trs pedals.
