Nebula, by Anker, Mars II Projector

Some background - I'm taking a week long trip with 3 kids (all 7 and under) and wanted a convenient option to keep them occupied during downtime. Typically I take a Chromecast and portable Wifi hotspot to stream video from apps on my phone. Somewhat of a pain to plug into a TV and use my phone to cast everything after connecting everything to the Wifi hotspot. Also, means my kids are laying/sitting on the bed to watch their shows. After some research I landed on the following requirements: portable, built-in sound, painless setup, Android OS, HDMI input, and decent brightness/resolution (HD preferred). I almost pulled the trigger on the Nebula Capsule when there was a $79 discount but was hung up on the lack of HD and low lumens. Fortunately the Mars 2 became available before my trip. Only 1 review at the time, but I pulled the trigger. Because this is my first projector purchase, I can't compare & contrast to others, but here's my current perspective on the Mars 2 after a week of usage:Resolution - it's 720HD. Clarity/sharpness is great (see autofocus). I don't miss the 1080 resolution (doubtful you will either). The size on the wall more than makes up for it. That said, don't watch SD video on a 12' projection - you will be disappointed. My 75'' TV has been sitting idle for the past week. A 12' screen is hard to beat for a movie experience. I listen through a bluetooth headset versus my 5.1 setup and but its still worth it. I'm contemplating buying a pull down screen in front of my TV and hooking it up to my 5.1 setup. Oh it also has auto focus - you shift the Mars 2 a little bit, it will automatically refocus. Pretty awesome. I read the other Nebula models were manual focus. I can imagine that would be annoying. Auto focus is a big deal. 300 lumens is bright enough for my usage. No interest in trying to watch movies/shows on it during the day. I would use my TV to do that if I ever had the time.Sound - it's built in! That's a big deal for me. Good enough speakers for the kids and their shows. Don't expect anything crazy - doesn't come close to my 5.1 setup, but it's way more portable. It has two 10W speakers. An Alexa Echo has a single 15W speaker so that's a reference. That said, I connect my Klipsch headset over bluetooth and it sounds good enough for watching most movies in stereo plus I don't disturb a sleeping house.Interface/Remote - it has all the major apps you would need (Netflix, Plex, Kodi, Amazon Prime, VLC) and it's WiFi capable. I don't have a need for anything else. Remote works just fine although it's IR based as long as you use it in the general vicinity of the Mars 2. I hooked up the Android app remote, but haven't had a need to use it. I like the confirmation sounds when moving the selection cursor around. Changing volume displays a ring overlay which depicts your sound level - basic, functional, simple = winInputs - have only tested the HDMI with a Chromecast dongle and it works fine. Does not support Chromecast protocol natively (whatever other reviewers may say) - it won't show up as an option to cast on your android phone or chrome browser.I suggest getting a tripod for it so you can level it at the right height if you are taking a trip with it. Has vertical keystone correction which works quite well with autofocus.I'm pretty happy with my purchase. It's a good mix of the right features for what I wanted to use it for.
