Light Stopped Working – Quickly replaced via Customer Service
Initially, this was a great light. The app provided many useful features for setting up the light to function in your environment. Less than a year after installation, the light stopped working. It does not even respond to the typical on/off/on/off/on reset sequence. It is dead.I have sent an email to customer service and will update this review if they respond.Customer service is critical. If their service is excellent, they will be back to 5 stars. If no response, 1 star.Update:Customer service responded in what I consider a timely and courteous manner. Without hesitation they shipped a replacement light. In less than a week from my initial email to Ustellar, I received and installed the replacement light. As I said before, customer service is a key element of a product rating. Ustellar stood behind their product. I would definitely recommend this product.The rating is back to 5 stars.

Works fine. As sensitive to motion as other models?
Installs easily. I really like being able to turn it on with Alexa – the main reason for choosing this model. I won’t brag about the sensitivity. Seems less sensitive to movement than the one it replaced – even though it is set to maximum. But works fine.

Stopped working after power outage
Worked great for about 6 months, paired easily and connected to Alexa. After I had to turn off the main circuit breaker for some electrical work the problems started. Once the breaker was back on the lights came on full time and wouldnât reconnect to the smart life app. Iâve tried everything to reset them including deleting them and re-adding them to the app, adjusting network settings and resetting the breaker again with nothing working, and cannot even get them into pairing mode. Be prepared to have these lights bricked if you have to kill power to them.EDIT- I was able to get in touch with customer service and they did replace the lights for free. So far the new lights are working perfectly, hopefully wonât have anymore issues.

Poorest mount design I have ever seen, worst software, worst instructions…!
It just blinked and blinked and blinked for 2 weeks .This review is best read while listening to the Mission Impossible theme.You start with a ‘Uge base , then they want you to mount it on a ceiling fan type box with just the center supporting the entire weight of the light???Its redonkulous! (There’s a donkey in that word somewhere, for a reason).Once you get this huge base mounted on a box, it sticks out from the house like a FOOT ! Ugly, wonky and extends past the overhang on the house so it’s exposed to the elements, which we all know is not what these cheap lights were designed to withstand.Sooo, I had to open the light, shave off the screw studs to turn them into holes.Then was able to mount it directly to the house with 2 screws and a hole for the wiring to passthru. Caulked and good to go.Shouldn’t have been that hard. Super poor design.-Now on to the wiring!Initial wiring was easy. BUT, because I was unsuccessful connecting to it to my home router, I had to take the light fixture on tour for the holidays using a 4 ft ext cord with wires poked inside (wide blade is the neutral, white wire). Cleared innocent bystanders from the Frankenstein area for safety and plugged it into the wall.-Now to the network…Unfortunately, most everything in our world is 5gz these days and many new routers won’t even broadcast a 2.4gz network to even log in. That presented a big hurdle for me. I suppose they chose 2.4gz for range over speed, but, wow, what a pain!I had to find a 2.4gz network I could log into for the light and my phone.My home router just wouldn’t connect for some reason.Tried my brother’s NEW xfinity router. No dice !Then onto my friend’s house.They happened to have a NAMED 2.4gz network (myhouse-2.4). Yay.Of course, my phone wanted to connect to the default 5gz network.I put phone in airplane mode .Had to disconnect from the 5gz network and force the phone to connect to the -2.4 suffix. That took a few tries. My phone just hates 2.4gz networks for some reasonð.-Finally, Opened the APP.App asked for location. NO.App asked for permission to take pictures and record video !! HECK NO!Bluetooth. NO.Had to enter the network ID and PASSWORD, no way around that, (more on security concerns later).-Looked for “Usteller spotlight”..not there.I chose “Add device “.Picked “lighting”, scrolled to spotlights section,picked “PIR Light (Wi-Fi)”.APP said to turn light ON.APP asked about the light FLASHING.I had to plug/unplug 3 times to get fast flash mode. Then App started scanning for the device .Finally it identified “Smart Security Floodlight”! YAY!It added it to the App and I was able to select it and enable motion detection.I just wanted full brightness, On for 1:20 when motion detected and then Off.Easy to setup once you jump over every hurdle they throw at you.Then unplugged light. Let it sit a while and plugged it up in a dark room.After power unplugged and plugged back in, it seemed to keep its programming. Thank goodness for small favors.Now I can throw it back into the trunk for the journey home in 2 weeks and hope it doesn’t de-program itself.I really just wanted a bright stupid light. But I can’t pass up a sale ð.- Alternative?I would highly recommend the wireless, solar, non-smart light over this one.It’s impressively bright, cheaper, super simple and super efficient. 4 minute install…not 2 weeks of holiday stress. All of our future lighting will be simple solar.You can find it here…https://www.amazon.com/gp/aw/d/B09YXPKGY2?ref=ppx_pt2_mob_b_prod_imageAbout The APP -I was able to find an app for SmartLife with a Googleplay search and downloaded. It’s overly complicated .At one point I hit a couple of help buttons and ended up with a CHINESE help page. Not very helpful.My concern is, why am I giving full access to my network and passwords and location to this Chinese app? Where is my personal information going?? Where will all of this private info ultimately end up?It feels like another Tick-tock fiasco waiting to happen.Apparently, you can’t just set up a fire walled LAN, the spotlight REQUIRES INTERNET ACCESS to be programmed!! WHY??I’ll be changing my network passwords and deleting this possible spy app once the install is complete. I hope it doesn’t leave a virus dug in somewhere.It sounded too good to be true…it is smart, but not easy.It seems the smarter appliances get the more stupid I seem to be.Overall, I just can’t recommend this product for various reasons .

Amazing Light, Smart and Very Bright
I installed one in my carport. It’s very bright. I have it turned down all the way and set to warm.It took a little bit of figuring out, but here’s how I set it up to schedule it with Amazon Alexa.I followed the instructions that came with it and paired it to my home network. Do NOT do anything with their Smart Home app after Alexa finds it or it will mess with Alexa functionality, trust me I had to delete everything and start over twice. All the light settings like brightness, color temp, and mode are included in Alexa.I set up three new routines in Alexa.One powers on the light at sunset in manual mode and shuts off at 11:00pmThe second powers on the light in sensor mode (no light unless it detects motion) 11:00pm until sunrise.The third powers off the light at sunrise. It works flawless.I bought the two pack but it turns out that one is plenty of light for my 22’x22′ covered driveway.Great purchase!

Will not stay set to motion detection
All in all, a good light but it will not stay set to motion detection. User manual states you can use a specific voice command (thru Alexa) to set it to motion detect mode. This command does not work. I contacted the manufacturer. They simply repeated what the manual stated and did not solve the issue. You can set motion mode via the app but once you use a voice command to turn it on or off, motion detection is cancelled.

Great Product, Great Price!
I bought one of these and installed it on the shed outside. Its right in the elements and hasnt had an issue at all. This thing gets really bright if you want it to, all controlled within the app. I have mine running through Smart Life and I can set a timer, turn it on or off, and even control the motion sensor. Overall this is a great product.
