    WORKING MORE THAN EXPECTED
  

*by M***C on Reviewed in India on 18 May 2017*

I rarely write reviews but I had to for this product.Received just yesterday... 2 days earlier then expected!!!  Thanks Amazon.  I charged the usb for 3 hrs and kept  recording mode  overnight. The device was still recording (blue light blinking) and  I switched it off and checked the files and I had the recording for 12 hrs!!!!!!  I will try again after charging for 3 hours and till the blue light stops and see how many hrs can it record Whether the claimed 140 hrs will be true or not.  I charge only 3 hrs because I am cautious of overcharging.  I am impressed by this device. Previously I had doubts after reading the reviews but now I recommend to anyone for this price.

    Stable but NOT a SPY product
  

*by A***P on Reviewed in India on 15 August 2016*

I used the product for at least 7 days and here is my feedback for those who wan to buy.Good Points:1) It works even after 10 times of recording. No failure yet.2) Highly sensitive to background sound. It can cover a room easilyBad Points:1) Very bad design - a sharp blue blinking light in the device will draw anyone's attention from distance. So it can not be used as a Spy product for sure. This is the worst part of the product.2) It can not filter out noise from running fan. So very difficult to get noise free recording. But I believe this might be a problem with all such products. Unless a high end and expensive product, it may not be able to filter out noise.3) Amazon delivery is not good. One can not plan his/ her work. Even I brought to notice of Sr Mgmt of Amazon and nothing was done in reality except a prompt courtesy response that action will being taken.
