Designed to enhance the accuracy and isolation of the TM-70T handheld tuner, the white CM-400 Contact Microphone from Korg offers superior tuning performance on a variety of instruments, including wind, brass, and stringed instruments. With its universal rubber-lined instrument clip, the CM-400 delivers faster, more precise tuning.
The Ideal Clip-On Tuner
The CM-400 is a clip-type contact microphone using piezoelectric elements that transmit vibrations directly to the tuner by attaching the microphone to your instrument. The CM-400 enables a more accurate tuning than the microphone on the tuner itself, and allows the tuner to detect the instrument's pitch more reliably, especially when practicing with a large group or in other environments where the signal is easily affected by other sounds.
Durable, Disconnection-Free Cable
The cable, which excels in efficient sound transmission, is made of a material with a soft and flexible wire sheath. The split shape of the joint between the clip and the cable reduces the load on the wire and makes it difficult for the cable to break.
Ultrastable Clip
The maximum width of the clip is 1.2", and the inner rubber part is designed to be attached to any instrument without leaving any mark or causing any damage. It can be attached easily and securely to a variety of instruments, such as the bells on wind instrument, the heads of bowed string instruments (such as a violin), guitar, bass and ukulele heads, and more.

A must have for active dogs
Size: Max Size, Size: Max Size
I normally do not write reviews unless a product is really good or really bad.
I have a dog that thinks chasing balls is the only thing in life and unfortunately she has a mom that has anchor pins in both shoulders.
We've been using this ball launcher for little over a year. It goes through about 32 dirty balls, 3 times a day and has held up amazingly. It is even full of dirt and still keeps on working, it looks like R2D2 went thru a battle. 😆
I recently bought a second one as a back up because I can't believe this poor thing hasn't given up yet.
I rotate the balls because my dog brings them back wet and muddy, then they won't launch as far, so I knock some dirt off of a dry one and launch it.
I would highly recommend this for active dogs.

DO NOT BUY! IT BREAKS EASILY.
Size: Max Size
DON’T WASTE YOUR MONEY! The first time I bought this product it broke within a couple of weeks. The conveyor belt stopped spinning making the unit unusable. The second one I bought broke within the first hour. Again the conveyor belt but this time it would spin uncontrollably even when the unit was turned off. We used the balls included in the packaging and with supervision which is recommended in the product pamphlet. I tried to reach out to All For Paws but was unable to locate a working customer service number. For the price it should continue to work without issue. Very disappointing.

Your dog Might Not Be as Excited as You Are
Size: Max Size
It arrived and worked as expected. Throws a good distance, not loud & easy to use. However, my rescue Belgian Shepherd (24/7 ball dog) was totally scared of it. Work with her for a week but she would literally avoid even being in the same room. Being she is rescue you never know what happen to them in the past. Moral of the story, just bc you have a full-on ball dog doesn’t mean they will be excited as you are. Unfortunately had to return.

Good but not great.
Size: Max Size-EPTU Balls
Good but not great. We had to return. We liked it first out of box BUT as soon as the balls got damp from grass and slobber they were not launching well.
