This tuner is wel suited for the bedroom guitarist, it simply does its job if you quickly plug your guitar in to tune and out again.
I wouldnt recommend taking this on stage or anywhere else. There are a few loose components in mine, and they rattle if you shake the tuner. And its not that ive been hard on this thing. Also, there is signal loss if you put it in your chain with other pedals.
And lastly, if you pick your guitar string, it kinda takes a while for the tuner to respond sometimes(like, a full 2 seconds sometimes in my case? but then again, mine is a bit broken)
But all this is quite normal with a 25 euro price tag in my opinion. If you want a tuner that must be sturdy enough for live situations, that doesnt produce loss of signal in a chain with other stuff, and thats really clear to see with leds for example, your looking at the wrong tuner and youll have to go look in a higher price range
