ENO MUSIC Solid Big Clip-on Professional Wind Instruments Alto Saxophone Tuner, Colorful LCD Display, Saxophone Accessories (Tuner, Black)

Nothing complicated. Works as advertised. Easy to use.

The supplier has bluffed about the size The actual size is very small.

I've had it for a few months and used it for some personal practice and band rehearsal sessions. I honestly can't find much to complain about here. It clips on easily, it comes with 2 watch-style batteries(but only needs 1 to work), and it can tune any instrument. The tuning is responsive, and the digital display is accurate as far as I can tell. The coloring on the display lets you know if your sound is leaning more sharp or flat as well, which is nice. Another small but useful feature I noticed is that pressing the power button doesn't immediately turn the device on. You have to hold it for about 2 seconds before it will power on. This is a good thing to me, because that means if it knocks up against something in my case then it won't turn on and waste battery life when i'm not using it. So long as this thing stands the test of time, which I assume it will since the only time I take it out of my case is to tune with it, then I'm happy with this little guy. It fulfills the job of getting ready to go and in tune a lot easier, and helps me dial in my gear when I switch things up.

Clips onto the lead pipe brace of horn. Miracle for beginners. Lets them know the pitch they are playing. Easy to read. 2 bad things. Battery has short life. All flats are shown as the corresponding sharps when all beginning music for horns has 1 or 2 flats and no sharps. I bought 4 and my 2 horn students each bought one. Transposes for trumpets, saxes, horns. Transposing tuners are RARE. I returned the $60 Korg tranposing tuner because it didn't hold a candle to these tuners. These are much more readable and accurate. In the clip mode, the tuners accurately read only the instruments to which they are clipped instead of randomly listening to all the instruments in the band. Will be using one of these myself when I go to band and orchestra so I can work on making myself more in tune. A must for any beginning horn student who is lost pitch wise.

Works well for about 15 minutes and then it stops detecting. So for practicing it is sufficient but I wouldn't count on it for a night of performance.
