This recorder FEELS great. It’s heavy enough to feel stout, but not so much that it would bother you. The menus could be laid out better, but aren’t that hard to figure out. I bought this for a strange reason. I am a ham radio operator who is CONSTANTLY listening to the police scanner. Everyone I know texts me, asking if I know what’s going on when they see police activity. Long story short, after hearing traffic a few times that I wish I could play back, I decided that I needed to start recording the police traffic in my area so I could listen to incidents after the fact. I have this recorder connected to the line out on my ham radio, using the mic jack on the recorder. It’s split, with the output going to an external speaker as well. When you start a recording with something plugged into the mic jack, it asks if it is “line in” or “microphone”. Using the “line in” option, without an attenuator, and at about 80% volume, it records perfectly clear. It CAN take line level input, up to a point. The speaker is perfectly loud for my needs at this level. An attenuator would make up for the last 20% of the volume on the speaker if I needed it. I don’t trust the no name SD card it came with, so I upgraded to a Samsung 512 GB card. I have it set to save off recordings in hour long increments (MP3, max bitrate). It’s averaging about 85 MB per hour. So about 200 days on a card that size. At that rate, I’ll just dump or wipe the recordings every 6 months, and offload anything interesting that happens. I wish it had a loop record option, so I didn’t have to remember to do that, but you can format the card from the menus, so it doesn’t get any easier to reset when it gets full. It’s also nice that the file names for the recordings are automatically named with the date and time they are started. (You can set it to constantly record and save off recordings at certain length intervals). When downloading the files, they show up as a USB storage device, so no confusion there! For $33.00, this is perfect for what I needed it for. Hopefully it doesn’t burn up from 24/7 use. I will update this review if it does. Menus and manual are chinglish, but they aren’t super confusing. UPDATE: This device, even when plugged into a charger, will not record 24/7. I'm not sure how long it stays on, but I went to check on this after several weeks, and it had powered off. I still think this is a great device, however it does not work for the application I outlined above for 24/7 audio recording. UPDATE 2: I had a 512 GB SD card in the device, and was recording in 60 minute intervals. When the number of files in the directory reached 200, it said it had reached the file limit. After switching to a longer recording length, it said my storage was full at about 100 GB. This seems like a great bargain for a good device, but for my use, it has too many shortcomings.

I’ve been using this 136GB digital voice recorder for a while now, and it’s been fantastic. The sound quality is very clear, even in a room with some background noise. The controls are straightforward, and the screen makes it easy to navigate through recordings or switch to music playback. Battery life is impressive, lasting through multiple days of light use without needing a recharge. The huge storage capacity is also a big plus — I don’t have to worry about running out of space anytime soon. Overall, it’s a reliable and easy-to-use recorder that’s perfect for meetings, lectures, or even personal notes. Definitely worth the price!

Have not used all the features as yet. Fairly simple interface, starting and stopping (automatically saves) recording with a single switch. The built-in microphone works well for voice recording. Sharp and clear recording at arms length. Have not yet tried the included clip-on mic. The Settings set up is somewhat intuitive - the lengthy instructions are helpful once you locate the section in the (literally) fine print. As observed, playback from the unit is not hi-fi with its fingernail size speaker. I saved in mp3 format so it was easy to save to my laptop and play them from there, much better! The USB cable is a bit short, but it works perfectly for file transfers and charging. I have not used it outdoors as yet, I'll see how it deals with background noise. Adjusting the gain will probably help with that. Smaller than my cell phone, feels solidly built, unlike my phone. Small screen requires my eyeglasses, but so does everything. Buttons are well sized, solid - note that the built-in mic will pick up the click if you are recording.

I bought this because of reported solid construction , that it was listed as Amazon first choice , price , and usb C interface . Most if not all future devices will be using usb C after the international conference a few years ago . It works very well for what I am doing these days . I will be using it to record instructions mostly on how to use my computer for paying bills , taxes , retirement jobs which my wife did when I was working. It works fine for long playback . It comes with long instructions because it is capable of doing many things if you want to do many different things. Just recording and playing back is actually simple and easy . I am a retired physician and had to dictate medical notes all day for 30 + years. If you are doing lots of dictation then a larger recorder that fits the hand and has larger buttons would be better . When you dictate medical notes ( and if you are a perfectionist ) you are constantly rewinding , listening to short segments , rephrasing to make it easier read later. This device is smaller and better suited for recording things like conferences. You can rewind and listen to shorter segments when you long press the rewind . Short pressing rewind would jump from one music track to another if you are recording music . I don’t do any of the music stuff . Overall excellent recorder .
