This is an excellent projector. I did research but Bestbuy does not allow you to test in store. So after reading reviews and returning a few others. This was a sure winner. You can connect to an external speaker - but I did not need to since this is replacing the TV in my room. I hardly watch TV so it is useful for my youtube workouts and watching netflix etc. Slingbox on this sucks as well, so please don't waste your money. The trial period is extremely short, so I was charged without even noticing. The streaming flickers a lot, so it's not worth it. The visuals are quite impressive, I have dark curtains so once the glaring sunlight comes in, I just close them shut and no concerns here. The quality is def what I needed and everyone has seriously given me compliments. It is also quite easy to use because of the touch screen and being able to download apps and browse the internet without some clumsy feel. I gave it one less star due to the annoyance of Casting. It typically does not pick up my phone even with casting on...and it's even more annoying that my phone will cast to my tv somewhere else in the house and not to this. But that's the only downfall. See attachements. LOVE ITTTTTTTTTT.

ZTE has hit a home run with this device. I had read about this device previously, and I couldn't wait for it to be available. This is a 2nd generation device, and ZTE has really improved from the first device. The SPro2 is a smart, WiFi capable pico projector. What does that mean? It is an Android (4.4 OS) powered device, which makes it smart. You can download apps directly on to the device (just like your would with your smartphone) because you can connect it to any WiFi network. I stream SlingTV, NetFlix, and GooglePlay content. The SPro2 also has 16GB ROM, so I can download movies on to the device (or business presentations) when there is no WiFi available. Since it is a projector, it has a 200 lumen lamp, and it can throw the projection up to 120". It also projects at 720p quality. At 200 lumens, it has been more than capable to deliver enough brightness for most indoor uses. The SPro2 has JBL speakers integrated into the device. The device fan is very quiet, and with the integrated speakers, the sound is of high quality. I have also connected my Bluetooth Speaker to the SPro2, and that is easy to set up and offers even more sound. The device supports HDMI connectivity. I have used this for business presentations from my laptop. You can also connect a USB drive or SD card for more memory or to access additional content. Lastly, it supports auto focus and auto keystoning, which are great added features. The package contains a carry case, HDMI cable, and a QR code to download a remote control app to your Android or Apple smartphone, The remote control is really cool, and it mirrors your projector display screen for easy navigation and control. I would recommend this device to anyone seeking the lastest in cool innovation. The projector is great. I love the Android interface the ability to connect to any WiFi network. This device has it all!

The ZTE SPRO2 SMART PROJECTOR is Technologically Incredible. I was so impressed that I purchased another one that I presented as a gift. This electronic marvel gets **********

This is the absolute best thing you could do for your kids and your movie night. I love the fact it has Wi-Fi and Bluetooth connectivity and it works slowly through HDMI. This unit is used when we go outside and project movies want to the garage door. Their software is flawless and his android so you can add a lot more. This is one of the best investments I have ever made

The ZTE SPro is a great little add on for a family movie night in the den or down in the basement. It's 1200 lumens and 110" projection capability make it a great projector for a dark room. I use mine in my basement with additional speakers to have movie night with the kids. The picture is sharp and impressive in a dark room. It is easy to set up and attach to your computer. It even can hook up directly to the internet using wifi. The two draw backs I've discovered are; the need for a dark room or the picture gets washed out in the light. and longevity. I found that after an average of 1-2 hours of use a day the machine began to over heat after just 6 months. Best Buy did a nice job of replacing it for me and I am not having any issues with the new one, yet. So, if the over heating after sustained use was a fluke, I wouldn't have anything bad to say about it. But we'll see. But over all, I like the projector. A crisp and big picture with good sound quality for as small and compact as it is as long as you have an appropriately dark room.
