Changed the battery, switched it On.. it doesn’t work. Waste of money.

Great piece of kit, easy to use as well as great price

Excellent product exactly what I was looking for easily connected and very concealable which makes it even better for covert work

It works exactly like I'd want for Zello.

iPhoneやiPadでは、PTT電子的にロックが効くのでかなり重宝してます。 ただし、Androidの機種には ロックが効かないようです。

This device operates exactly as promised. I’m currently using Zello on my Samsung Galaxy S21 Ultra, paired seamlessly with my Samsung Galaxy Buds Live earbuds. Once everything is configured, it enables me to simply press the Push-To-Talk (PTT) button, communicate effortlessly, and hear everything clearly through my Bluetooth headset—without encountering any connectivity issues. There is a slight delay of about half a second after pressing the button before I can start speaking, but it's manageable. The battery life is impressive; I keep it powered on consistently without worrying about it running out. For the price point, it’s definitely worth the investment, especially for anyone who frequently uses the Zello mobile app. If I have to point out a drawback, it's that the on/off switch is quite small and inconveniently located; you'll need to disassemble the device to access it. This can be a bit of a hassle, but overall, the performance makes up for this minor inconvenience.

We use Zello while driving cross country. These buttons save having to keep the phone at hand and comply with cellphone laws. Very convenient when phone is paired with the vehicle or earbuds/headset.

This little button saves me so much time doing my fire inspections it's amazing. I don't have to pull my phone off my belt to push the button on the screen to communicate. I have my Bluetooth in my ear, my phone on my belt, and I just push this button to speak and I hear the response in my ear. I usually just strap the button to my belt with the Velcro band it comes with, but you could place this thing literally anywhere on your body you wanted. I didn't even have to pair it with my phone. I simply turned it on and went to the Zello App, pushed the button once and it paired instantly. BTW, I have an iPhone 12 Pro Max that I use it with.
