I have a couple of Peterson Strobe tuners, and the Snark was always on the money.
My issue with the Snark's is they go through batteries, and they get dim after a while. You can get them to brighten by pushing on it or smacking it, but eventually they didn't work.
The other issue is there is a range of frequencies where you can hear the tone change but the indicator doesn't change. I have a Fender tuner that is really bad because of that. The Snark isn't bad.
The Peterson Strobes are much pickier at getting the frequency dead on to get it to stop moving. Almost too much so. You spend a lot of time chasing the strobe.
For the money you could buy 4 or 5 Snark tuners and throw them away when they quit working and still be cheaper than a Peterson.
My wife refuses to use the strobe tuner, and even my guitar playing son said he doesn't like it. But of course he can just tune by ear, the JERK!
Don't take anyone's word for anything. Not mine either.
