I bought this one during pandemic. My children use this to watch movie every day. it worked very well until it didn’t work. The customer support sent me a new one immediately. Because the pandemic, they allowed me to send back the broken one after the pandemic.

This worked well for nearly a year. I dealt with quirks of native support for only a few companies (Netflix, Amazon, and YouTube) and rather enjoyed the picture quality and portability.

The fan broke recently. Thankfully, Anker Support has reached out to help me. I'm upping my review to 4 stars for the moment and will either bring it back down to 1 star or 5 depending on if I can get my device fixed or replaced.

There is no other projector comparable to Ankers Mars Nebula projectors. Rechargeable battery, built in app, amazing built in speaker, hard drive file system. A+++

One of the beat electronic product purchases I’ve made on Amazon. I’ve owned this for over a year and I love the portability, auto focus and audio quality. The picture quality is very good for the price. The audio is very good and loud for a small room. Some apps are difficult to load on the inbuilt software but the app support has improved considerably since I bought this back in early 2019. I usually get around this buy connecting a Chromecast to the HDMI port on the Nebula. Great product by Anker!

Well it worked very well until it didn’t. Lasted a year and a half.

Update: I contacted customer service as the unit would start whirring but the light and projection would not appear and the whirring sound would stop. Their troubleshooting was:
“ This is an unusual issue for our Mars 2. To further figure out the problem, could you please see if the following steps resolve the issue and let us know:
- Fully charge the unit with the power adapter
- Reset the unit by plugging a pin into the reset hole on the back of the projector when it's plugged in.
- Slide down the lens cover with a little bit harder force.”
The last bit worked for me- I guess there must be a connection to the projector that the lens cover controls- perhaps that becomes less secure over time? Anyway, it’s back up and running, excellent picture quality in dark living room (good enough sound for me/ average person) and I am fully taking advantage of winter rain and long nights to use this!

Also I appreciate the customer service and that the advice actually worked! So 5 stars for this one.

I will say laptop connections may be far easier- no support/ app on HBO max or Disney plus, but an HDMI cable solves that.
