A Lifeline for Recovery

This interlock device has been essential in my recovery journey. It keeps me accountable and has helped me stay sober. I wish the calibration reminders were a bit more frequent, though.

Average Device

The interlock device does its job, but I've encountered some frustrating issues with it not recognizing my breath. It's decent overall, but I expected better for the price.

Works as Advertised

The Best Interlock Device is effective and did exactly what I needed it to do. However, I did experience some hiccups with the initial setup that could be smoother.

Good but with Some Drawbacks

While the interlock device works well, I've noticed it can sometimes be a bit sensitive. A couple of times, it has made me blow again for no reason. Still, I appreciate its effectiveness.

Not the Best Experience

I had a frustrating experience with the installation process. It took longer than expected and the technician seemed rushed. The device itself works fine, but the service could improve.

Easy to Use

Using this device is straightforward and it provides clear instructions. I’m glad to have it for peace of mind. The only downside is the size; it could be more compact.
