Let me start by saying this little gadget is a mixed bag of surprises. The 128GB storage (64GB built-in + 64GB SD card) is an absolute game-changer - I dumped my entire music library (yes, even those embarrassing 2008 emo playlists) and still had room for audiobooks. The Bluetooth 5.3 connection held strong during my subway commute, though pairing required some menu diving that wasn't immediately intuitive.

The built-in speaker shocked me with its decent quality during backyard BBQs - not audiophile-grade but perfect for casual listening. That said, the volume scroll wheel is this device's Achilles' heel. Mine worked fine for two weeks before developing a mind of its own - sometimes turning clockwise would decrease volume, and it'd randomly cap at volume '7' like some rebellious teenager.

Battery life truly impresses - I got about 15 hours of continuous playback with Bluetooth on. The 2.4" touchscreen, while small, responds well to swipes but becomes frustrating when trying to create playlists (limited to just 3?!). File organization feels archaic - you'll spend more time browsing folders than your local librarian.

Pro tip: Don't bother with videos - the MP4 support is practically nonexistent despite claims. But as a pure music player? Once you learn its quirks, it's a nostalgic powerhouse that fits perfectly in your gym shorts pocket.

The verdict:

- ✅ Buy if you want massive storage & reliable Bluetooth

- ❌ Avoid if you need intuitive controls or video playback
