Purchased the unit in the end of 2024. Let's start with good - metronom is flexible and loud enough - can say the best on the market (I stick to that daily), tuner is nice looking and looks reliable. Negative points - tuner does not work corectly in "air" mode (mix up the notes or do not react at all) you need always use cable connection. All connections to the unit you need to make through any kind of explorer (Safari does not work) there is no good application to tune the unit up. Creating of own metronom patterns is headache. Hang up, slow, doesn't work at all - this is the point for producer to improve. My decision was to use it only locally without any connection to the lap top. In 2025 made decision to download new firmware update. No connection to the laptop. USB burned out. In total I used USB connection 3-5 times. In my life I don't remember any problems on any devices with burned USB. But obviously it happens one day with any unit. Unit was sent to Musicstore service to repair. Their reply - 4 weeks minimum for service. My letters Musicstore to find solution to speed it up - no reply. Then made decision to contact Peterson directly. The next day solution was found. I am happy continue to use the device on my daily basis. My conclusion - there are different electronic devices on the market for different applications. Some are better, some worse, some can get electronic problems. But the key point - is Who stands behind that. Can only confirm reputation of Peterson and the people who drives the business. There are less and less companies who are still interested in their customers. Thank you Peterson Team for your help!
