Excellent price for a product this powerful. I compared it with others and this model is by far the best.
Very impressed with the sound quality much better than expected. I used it in a vehicle and could hear every word clearly.
The GSM audio monitor is brilliant. I can dial in any time and hear what’s happening. Helpful tool for checking on elderly relatives. Highly discreet.
Exactly what I needed. Helpful staff, fast delivery, and does the job.
Honestly better than my phone‚the mic. Very discreet and clear.
