I've used it for a long while now so here it goes, Works awesome, I can get SiriusXM YouTube and etc, BUT If you use iTunes, do not, again, DO NOT update the itunes app, it'll just say that its "rooted" for some reason and it won't work, if you do, you came just do a Factory Reset in the Settings and Re-Download your songs and so fourth The good things Great screen, good sound, I can read good with this screen I'm a cart att in90 to 100 degree weather and works just fine, my hands are medium sized for a small device Comes with the SD Card and a thick Cass for it with those stupid skull candy ear plugs which I don't like but I like it

I like the profile and functionality of it. I got it specifically to be able to run SiriusXM on it while in the shop on bluetooth and wifi so i didnt have to run the app on my phone anymore. It took about 5-10 minutes to set it up and with the Android software, it was simple. after charging it, I was up and running in no time. It took me longer to delete the apps I have no use for or was never going to use. It seems quick and intuitive, very clear, quality display. Clean and simple. I havent put any songs on the SD card yet and wasnt intending to as it was purchased specifically for the Bluetooth, wiFi and being able to use my SiriusXM and its worked perfectly so far for my application.

I'm in love with this mp3 player. the sound is super good, and loved the apps installed in it. The durability of the battery is acceptable. Is super easy to travel with this because is small and light. And the most, is not slow, the mp3 don't freeze in screen and I see have a good RAM MEMORY. I found it super versatile and quick operating system. I didn't had any problem with the connections.

08/06/2025 Back to 1 star. This mp3 player overheated and corrupted the microSD, losing valuable data. Just don't buy this. 07/28/2025 I'm updating my review after a few months of usage to two stars. I would like to acknowledge the seller, who did offer me a full refund. However, I was tired of the situation and never took them up on it. They do deserve credit for that. Also, I've gotten too used to devices arriving with some state of charge in them; this mp3 player was just dead. A good charge fired it right up. The Good: 1) It's a neat size and fits comfortably in my hand. I'm more accurate on its smaller screen keyboard than I am my 6.5" phone. 2) USB-C! One plug to charge them all! 3) And it's cute, I really like the red color and the "glass"(?) back, it's very aesthetically pleasing. 4) Storage. The accompanying 64gb MicroSD makes this a storage powerhouse for its diminutive size. The Bad: 1) It will forever be the battery issue. I don't know what kind of battery it is, but it is not managed well by the device. It will get extremely HOT with extended usage, even with screen dimmed completely. You should NOT leave this device unattended to charge, it is a fire risk. It CAN be charged, but only if the device has been left to cool completely. 2) This version of Android is outdated. I'm never on the cutting edge of technology, but the fact that I cannot simply insert a USB stick (with adapter) and load/unload files is sad. 3) Wireless connectivity issues. I specifically purchased this to play white noise at night while I sleep. Whenever connected to my Bluetooth speakers, this specific device will suddenly and constantly lose all wireless connectivity, it disconnects from my Bluetooth (with accompanying signal sound) and loses Wi-Fi connection, then randomly reconnects 30 seconds later. To be clear, this is not an issue at all with my speakers, Wi-Fi, or with any of my other devices newer and older; just THIS mp3 player. Conclusion: Don't buy this, especially for this price. The seller seems to be a nice person, but they're unfortunately selling, at best, junk; and at worst, a danger to the user and their home. Original Review: 1 star I bricked the first one with an accidental factory reset, but the device doesn't display the option to log into your Google account to unlock it. So I ordered a second one, and this one doesn't even turn on. For the 20 minutes I did have a working MP3 player, I was concerned by how warm it got so quickly. I'm getting my money back. Save yours.
