I bought one for us. And to be honest I was VERY SCEPTICAL. But once installed the sky is the limit on what you can do. Our kids are grown with their own children and even the grandchildren know how to operate it and love the video options. So we decided to get them their own and not to brag but mom and dads gift were the bomb. Even the grandchildren were excited
After having it for a few days I love it! I tried it with different cups and mugs and you’ll want to use the a mug with a flat base to really spread the heat. I pre heat my mug while my coffee brews and it will stay hot as long as you’d like. I found the default high heat setting worked best for me. It’s not to expensive and makes a great gift. I got mine in black and it looks great on my desk at work.
This thing really works. If you are reading a review that says it doesn’t then they r either not using it correctly or using the wrong product. I did not get paid to use this product or my personal opinion like others. I didn’t want to spend all the extra money on a fancy brand name with the same results. My pics will speak for themselves.
Arrival a few days before the scheduled date, very satisfied. Well packaged, received intact and functional, perfect for sketches, simple design but good for the price. Comes with an anti-loss strap, and the pen easy to store.
