My first impression was pretty good—I unpacked it, plugged it in, and it started warming my coffee almost instantly, which was a relief after dealing with cold brews for so long. As a sales manager always running between meetings, this has been a game-changer; no more rushing to finish my drink before it gets lukewarm. I use it daily at my desk and even take it on road trips, and it's held up well so far. However, I could be wrong, but I feel like it might not be the most durable thing out there, and for the price, I expected a bit more oomph. Still, it's a handy gadget that does what it promises, and it's made my coffee routine a lot better. :)
- Pros: I was extremely pleased with how this little device keeps my coffee warm all day long without making it too hot or letting it go cold, just what the doctor ordered for my busy schedule. It's super easy to use—just plug it into any USB port, and it starts working right away, which is perfect for my desk or when I'm on the go. I love that it's small enough to carry around in my bag, and it fits most of my mugs without any hassle.
- Cons: On the downside, it could be a bit more powerful; sometimes it takes a while to heat up if my drink has already cooled down a lot, and I wish it had a way to adjust the temperature since it feels a bit one-size-fits-all. Also, while the courier called ahead for delivery, which was nice, the packaging was a bit flimsy, and I'm worried it might not hold up well over time.
