128gb recorder is top notch, quality built product with extreme battery life. VOX/VOR can be selected via a tiny switch which is much easier than editing the mrecset.txt file every time you want to switch it. Once I set the time it was ready to record and record it did, the entire office is clear as a bell, stuck it on the side of the file cabinet and the recording was even clearer (I guess the file cabinet acts as a sound board). Little to no delay in VOX/VOR mode depending on the level of voice but I had it trimmed down so the fans wouldn't set it off. (Yes, VOX/VOR is sensitivity adjustable via the text file. Battery drain is unbelievably minimal in either mode as this product is mainly battery and I have no doubt that it would record continuous for well over a full week at a high bitrate. The recorded file time can also be adjusted, I have mine set at 1-hour so that it saves the hour of audio then starts a new recording (this makes it really easy to locate the time period for your desired recording.Overall I am very pleased with this product and the seller has gone out of their way to answer any questions and remedy and issues. I would give this seller 6+ stars if I could.Highly recommend this product.
