I purchased this microphone to use on a guitar for live sound. Works great for live and recording. It's quick and easy. It has a warm and natural sound. I would purchase another if needed. As with all AT mics I've owned, great quality and value for the price.

I bought this for recording and performing with several obscure African instruments (segaba, karimba, and chipendani). These are instruments with very hard to reach "sweet" spots; normal mic technique did not do them justice. Has met all expectations.

This extremely small lav delivers great audio, and its diminutive size allows for it to remain virtually unseen in the shot. I highly recommend it for controlled interviews.

the sound of this microphone is warm and it has a good presence in the low medium, It's a complementary solution to other more aggressive products of the market. It can be used in noisy conditions.

I like the clarity. Not quite as compact as I'd hoped, but if you're not trying to hide, it does the job well.

This is a good lav for the money. It has a nice warm sound and is very durable. We have these all over the studio and they never give us any trouble.

Small and out of sight, great quality. Just like The Tuck Pendleton machine: zero defects.
