i expected this to be a simple fix for my cold coffee problem and for the most part it delivers it heats drinks steadily without any fuss and the small size makes it easy to carry around i use it daily at work and on the road and it's reliable but it's not perfect it takes a while to warm up from cold which can be frustrating when i'm in a rush overall it does what it says and i'd recommend it to anyone who hates cold coffee like me
- Pros: it keeps my coffee hot without burning it which is great for long workdays and the fact it runs off any usb port means i can use it anywhere like in the car or at my desk no more cold coffee during commutes or coding sessions
- Cons: it can be a bit annoying that it doesn't heat up super fast so if i forget to plug it in right away my drink stays lukewarm for a bit too long and it might not fit all cup sizes perfectly which is a minor hassle
