The STronic UR225-135 has incredible voice detection mode of 225 days. That is more than almost any other device available. It uses the same chip set as the STronic UR125-075 but comes in a completely different shape. It is extremely thin, only 3,5 mm yet it has a higher capacity.

Another key feature of this device is the simple and easy to use design, it has one switch that you can put into two positions. The first is continuous recording and the second is voice activated recording. 

The recording time goes up to an incredible 135 hours when you take the size of the device into consideration. The device comes equipped with great microphones, which give you the ability to listen to up to 10 meters away.


  • Control – Simple control ( 3 positional systems, ON/OFF and Voice activation)
  • Microphones – Very sensitive microphones, which are able to pick up voices or noises in a radius of up to 10 meters.
  • Size – Miniature size 97 x 80 x 3.5mm makes this device ideal for pocket usage. It is easily operated with a tip of your finger.
  • Battery life – Incredible battery life; this spy recorder can go up to 225 days in voice detection and 135 hours of continuous recording. These values can vary based on the battery type.
