Great while it worked, pretty tough screen. It still worked after being half cracked..but one day it just wouldn't charge..
It needs really good phones to work well..
Video feature is great, speaker is Meh..

Works well but is complicated to use. Wish it had FM radio

I have tested 3 of the six cheap music players, and this one so far, and I don't see it getting beaten, punches WAY above its weight. $50, decently large 4.5in (480x800) IPS screen with an interface and navigation scheme that's not dumb. The other two which are also touch based, have obtuse swiping gestures, but since this has a home and a back button, it feels familiar to those who have used Android (this doesn't run Android).

Pros (THERE ARE A LOT OF THEM)
-Great screen, decent enough resolution and is truly IPS, now it's not 178 all angles great, but it's far better than the cheap TN panels I've dealt with with the other two 10 dollar cheaper media players.
-Features: Good features, randomly has a built in dictionary, I don't know why, but it's there and it's kind of neat. The on-board microphone is actually pretty decent, sensitive, and you need to do some post processing to mitigate background noise but better than just throwing a cheap one in there.
-User Experience: Everything seems to work, you touch it, and it works, has press and hold to enter selection mode and then can easily add multiple things into a collection when in music mode to make a playlist. The keyboard that's on screen for the dictionary is nice and responsive, also not very small, very usable on this tiny device.
-Quality: for $50 you're getting a lot of it here, decent screen, above average built in speaker that gets decently loud enough, a 4 pole headphone/mic jack. A microSD card slot that can ACTUALLY accept cards larger than 128, tried a 256GB and it hadn't any issue. The build is great, glass and metal where you need and want them Comes with a decent silicon case and two screen protectors. Thing charges up fast thanks to USB C, during a 15 minute video transfer, it topped off the battery as well which was about 50% full. Decent brightness and darkness with no real light bleed or issue. Came with a very weird 4 ended connector, don't know what that's for. It's a micro b and usb C connector on both ends, with both connectors coming out to form a Y. Very interesting and unique cable. Also, the headphones, something this cheap comes with decent headphones. The cable is braided, and the quality are nice, not Samsung Galaxy AKG bundled headphones nice, but not cheap dime store ones either, the earpiece is metal as well. AGAIN, a lot of weird quality for such a budget device.

Cons:
Music Play Back: Music sounds fine, and in and of itself, plays well, too. Great scanning and searching feature, no lag skipping through a song to get to a hook. THOUGH, and this is an annoying THOUGH, seems to have a big bug. When playing songs from a folder it will sometimes play a random song besides the one you pressed. I don't know why that is. One theory and not enough testing has happened to verify it fully, is that if you play a song from one folder, and then go into another folder and decide to play a song from that folder. It doesn't interupt the song and change to the new one, it plays a random one which I think is in the previous folder that the song you were listening to but in the position you pressed. So song two from folder A would play even if you press song two from folder B. Very odd.

Keep in mind:
This isn't an android device or a proper ipod touch like device, keep expectations realistic. I loaded an 8GB video from my SD card and it took a while to lode, and initial playback was weird. Audio syncing issues that seemed to correct itself when enough of the video got buffered. It played well after that.

While the screen is IPS, it's also prone to washing out, which was more apparent in the video test I ran.

This also doesn't come with ANYTHING but the dictionary installed as far as content goes. No photos to show off the good display. No sample music to test that out. No video sample either. BUT, OTG works flawlessly.

SO FAR, this is a huge recommend.

My initial impressions are good. I have only had and used the player for 1 day so far, but I think I will like it. Some things that can be improved however, it does have Bluetooth, but you'd never know that by reading the "manual" which doesn't mention it at all, nor is it displayed on the product box. When you look at the Amazon ad, it shows a picture of pod headphones. I got the impression they were included - they weren't. Not a big deal, but I think that could be spelled out to "provide your own". They do come with wired headphones which are good. Generally it is easy to use. I am a Windows guy, so I plug into the USB port and can drag and drop content to load up the player. When I initially plug in the player to load content, the device is completely empty...no existing folder structure exists - you basically create your own (at least that is what I did). There are 3 playlists visible on the device, but no instructions on how to use them. I have no idea if I am to create these on my PC and drag onto the player - and if so where or do I have to create them on the player??? The shuffle feature seems to work - I think, but seems awkward. I have a file structure of different folders for different music. When I turn shuffle on, what I experienced today is that it will play several songs from the same folder then switch to another folder and play one or more and so on. It's a little less random than I thought it would be. It also played the same song twice in a row while in shuffle mode (there are about 850 songs on the player) so in theory it's possible to come up with the same one twice in a row, I was surprised it did. The last comment is I think the manufacturer should rewrite the manual. The manual is written in English, but poorly put together. It was not created by someone fluent in the language. There are things missing (for instance are we suppose to charge it upon opening the box, how do we use the playlists, how do we copy media from computer to the player - do we need to setup a certain file structure, etc). Perhaps you don't think that is necessary since it is intuitive. I've used computers for more than 30 years so I can generally figure things out, but what about your customer who is relatively new to this.

I tried a DIFFERENT MP3 player that 1) didn't allow sorting by album artist vs song/contributing artist (so, let's say the album was BB King but a song on the album was BB and Katie Webster, then it separated them as two different listings) and 2) didn't have a search function or a "jump to" alphabet browser. That one held up to 80GB and with that much music scrolling on a small screen that only showed 3 or 4 items at a time was just not functional.

This player addresses all of those issues AND can hold a micro SD up to 512 GB, with a slightly larger (but still compact- about the size of my palm) screen. Overall: very easy to manage, lightweight, and it easily connected to my Bluetooth devices.

I've had a few hiccups: the first one I ordered wouldn't show up as an external drive on my computer, but it was quickly replaced and the new one does- a couple of times I had to shut it down and restart if it went to sleep on its own in the middle of loading too much music at once. Minor issue.

The main limitation that I would think could be remedied is that while you can select a folder from storage to add to a playlist, it only works if the music files are directly in that folder, but not if the music files are in a subfolder.

Example- I organized my files by: genre-artist-album(s), so: Blues-BB King-Album 1, Album 2. If I want to add ALL of my blues music to one playlist, I can't just click the Blues folder and have all of the songs in the artists' and albums' subfolders added in. I can go to BB King and select both Album 1 and Album 2 and add all of the songs in those two folders at once, then go back to the next artist, and so on.

For a device that can hold up to 512 GB, this is a limitation on the otherwise strong music management system that should be fixed because even the standard organization when ripped uses album artist as the primary and album titles as the subfolders.

I'm very happy with it, overall, I just REALLY wish the building of large playlists were easier. I've just loaded 50+GB of music onto it for a big vacation and I'm thrilled it also has the 3.5mm jack to plug into my car speakers since I don't have bluetooth in there.
