Only lasted 2 days
Im a taxi driver, needed a covert recording device due to false complaints. It was working fine and then I noticed it had become very hot and the red light remained on. Now it doesn't work - PC doesn't recognise it and red light stays on regardless if switched on and off.The recording quality was decent. But the one button operation is a recipe for disaster as I have experience with this and am always wary of such power on/off mechanisms. Difficult to know when its recording or not and of course the black on/off writing is only readable by a 12 year old with perfect 20/20 vision.The magnet is OK, but not strong enough for a car and of course it dropped under the seat and was such an ordeal to find.The recording quality is more than acceptable. Removal of background noise is very easy if you use an AI but I suspect it does have some kind of built in noise reduction which isn't bad. I just needed more background noise removal due to car/road noise. If you have this is a quiet place you wouldn't need to use any post processing. The mic is omnidirectional and it manged to pick up people in the back of the car from a position under the steering wheel so not bad at al. And as I mentioned the quality is very decent.So, not the worst, not the best, but as is very often the case these cheaply made devices do not last and in this case 2 days. I suspect it doesnt like to be turned on and off often. I dislike returning items as it can be a hasse, but in this case Im not paying an overpriced £40 for a USB drive failure. And thats the thing folks - this is just a cheap USB drive with a mic built in and will be susceptible to whatever can go wrong with USB drives - and they often do. The best thing about it is the recording quality. Just a shame its cheap tat created for a fast buck

Clear recording but has its issues
I was after something like this to be able to record meetings so that I could transcribe them later and make sure that I hadn't forgotten to action anything and this is just perfect for what I need.I don't need the complications of combined recorders and MP3 players and wanted something that would work and record with one click of a button.I also didn't want a big device as I have enough to cart around most days as it is. This device is very small (0.9" x 0.37) and charges with the included USB-C cable. I havw however noticed that this will only charge and function correctly with the cable included with it, rather than any USB-C cable. It's also a bit flaky, (the data transfer tends to fall over if the USB is fitted in one particular way into the unit rather than the other way, which is a bit odd, as it fits both ways).A tiny light shows blue on the back of the device when it's charging and a full charge will give around 18 hours of use.Another downside is that there is no way of telling what charge is remaining on the device, and the way it works is that when the battery is flat, it will just cut off from recording (after saving the file), which will make things difficult if you are not recording something that you think you are.Having said that, I do really like the easy operation of this. There's a tiny slide switch on the top which switches on or off. It's voice-activated, so will just record until it switched off by the little switch. There's no hassle in saving the file, as the process of switching the device off automatically saves the file which can then be viewed by plugging in the USB to your laptop and browsing to the relevant drive. The files are solved in a WAV format which then can be listened to via a media player on your laptop, or can be transcribed into Word etc.There's 16 GB memory inside this unit, which, as the files tend to be only quite small, will give you around 200 hours of recording before the drive is full, but I tend to delete them once I have listened to them or transcribed then.When the device is set to on the tiny status light turns to a static red and then flashes a few times in succession and then goes off, so again, you are not entirely sure whether it's recording or not, (but it does say in the instructions that when the red indicator light goes out, it means it is in the recording state), however, I would personally prefer if you could see it all times if it's recording, but there's no way of telling until you come to view the files at a later date. (I've already missed one recording I need because of this, which is very frustrating.)Yes, this has its faults, and it could do with showing for definite the charge and to give an indication that its recording all of the time that it is, but all this aside, it's a subtle little device, and magnetic too, so you can attach it to something whilst it's recording which is handy. The recording is clear as well. An equal measure of pros and cons with this.
