Bite the bullet and buy the Korg tuners. You don't need everyone to have their own metronome on the stand, don't buy the TM model, buy the CA-3 that's just a tuner. Cheaper tuners are slower to read and "settle."

The only feature I wish they had is transposing. Some of the cheaper ones can be set to transposed pitch instead of concert pitch. It's not super important, and not worth buying a less-capable tuner.

The clips are all flimsy. The Korg clips are the least bad among them.
