Anker's sub-brand Nebula is currently discounting its newest portable projector, the Mars II. Bringing the price down from $599 to just $429, which makes this a really good price for those looking to pick up the Nebula Mars II right now.
This projector does not do 4K resolution, but instead does 1280x720, at up to 150 inches. It also has 300 ANSI lm brightness, and DLP IntelliBright technology, which is still going to provide a crisp and bright picture for you. Nebula also has fast 1-second auto-focus available here, so you can set this down at any angle and it'll immediately auto-focus so that the picture is no longer blurry. That's definitely a good thing here, as the last thing you want to do is readjust the picture. For audio, Nebula has dual 10W audio drivers, which have been designed to deliver deep bass and cinematic sound. It also offers up 360-degree sound, so that no matter where you are sitting, you'll get a great experience here. Inside, the Mars II is running on Android 7.1, which means your favorite apps are supported. This includes Hulu, Netflix and other apps. Chromecast is not supported but some apps can be mirrored. This is a great projector to pick up, especially if you are looking to go camping this summer, you can still watch movies and such outside.
This item is also eligible for Amazon Prime's free shipping. Which includes free two-day shipping, and pretty cheap (usually $3.99) next-day shipping if you need it extra fast. If you are not an Amazon Prime member yet, you can sign up for a free trial of Amazon Prime. You'll get 30 days free (if you're a student, you get 6 months), and then it's $119/year (or $59/year for students). Prime members do get a whole lot more than just free shipping though, so be sure to check out the full benefits.
