We have all of these portable heaters/fans and they all work great! The top two put off great heat and are oscillating. The white one can also cool and does a great job at that as well. They come with remotes which is always handy and will quickly warm up your space. The portable fan is great to have for outdoor functions like games, camping or a day at the beach etc. It’s also great for a bedroom or office space. You can plug it in or charge it to run on a battery.
