Okay, so I snagged this Sunrisesu immersion heater to warm up water for my outdoor projects and, honestly, it's pretty rad. First off, it heats up water fast. Like, shockingly fast. I filled a bucket for washing my brushes and it was hot in minutes.The auto shut-off is a great feature, especially since I'm a bit forgetful. It kicks in around 158°F, which is perfect for what I need. It's also super compact, so storage is a breeze.Now, a couple things to keep in mind: it's powerful, so you need to make sure the whole thing is submerged when you plug it in. Common sense stuff, but worth mentioning. Also, it's not for huge volumes of water, like a pool or anything. But for buckets, and stuff like that, it's perfect.Overall, I'm stoked with this little heater. It's made my outdoor projects way easier, and the price is right. Definitely recommend if you need hot water on the go. Just be safe and you're good to go!
