Review: Returns for safety reasons. - From the moment I turned it on it heated up, not a little but to the point I had to set it down.

### ⭐ Returns for safety reasons.
*by M***L on December 22, 2025*

From the moment I turned it on it heated up, not a little but to the point I had to set it down. I turned it off after five minutes and returned it for safety reasons. The design was cute, came with a nice cover, but it was really heavy and had battery issues causing it to overheat.

### ⭐⭐⭐⭐⭐ Nothing over the top.
*by E***N on September 23, 2024*

Review update: The Swofy customer service team has reached out and are taking care of the issue update rating to 5 stars because of this. So I'll start by saying that this little mp3 player has a solid operating system powered by android. The OS is sluggish at times, but overall I haven't had to many crashes. This thing is really compact which is a us for me. The mp3 player feels premium in the hand because of the weight. The battery life is terrible for having a "2000 mah" battery and I feel like it takes longer to charge it than it does to use all of the battery up. It does come with some pre installed apps, but most of them can be deleted if desired. If you buy the blue one just not it is black on the backside. I would assume all the colors are like this, but I cannot tell you first hand. Ultimately it is alright, but is a little lacking for me.
