LEMFO Smart Watch, LEM8 4G LTE Smart Watch for Android Phones, Mens Smart Watches for iPhones with Android 7.1.1, 2GB + 16GB, SIM Card, 2MP HD Camera, 1.39″ AMOLED Screen, Bluetooth, HR & Step Monitor

I am not sure whether the existing reviews are from real users. The watch is huge and heavy and does not feel premium at all - it has a plastic feel. Certainly does not feel as something that is worth over $100. Charging piece is a flimsy cheap plastic that falls of the shelf due to the weight of the microUSB cable when not connected to the watch.But the main issue is that it is simply not usable on a day to day basis because of the battery drain. I wanted my son to have a watch he can use for few calls and text a day to replace his aging Galaxy Gear S2 (so he does not need to carry a phone when he is out). I hate the fact that the Samsung Galaxy watches have e-sim that ties me to a specific cellular provider and cannot work with a cheap cell plan so I was looking for a watch with a sim slot that supports 3G or LTE bands for U.S. carriers.Before I gave it to my son I tested it for a little over a day with an ATT sim (the watch gets great reception, by the way). Set up my son's google account and the only Apps I downloaded were "Find my Phone" and Google Assistant - both Google own apps.Set the watch to have screen off unless I move my wrist (then it shows time), Bluetooth off and wifi off. LTE on. The watch came off the charger at 6:30am with 100% battery. At 11:30am, 5 hours off the charger, after literally three 2-5 minute phone calls and 3 text messages the battery drained to about 30%. I did not use any app or played with any feature. Just had it on me seating at my desk during that time.There is simply no way this watch survives normal all day use as a stand alone device. Perhaps if you don't use it as a stand alone watch, but then what's the point? There are other nicer, cheaper alternatives with all day battery.I just don't think that a full version of Android is efficient enough to power a device with such a small battery for more than few hours no matter how you use it. At least with an always on cellular connection.I'm still looking for a decent watch that can receive texts and calls as a standalone device with a sim slot, will look OK on a 10 year-old and will last all day. This watch is not the answer.

The media could not be loaded.  The smartwatches I used before used either Wear OS or watchOS. Of two different OS, I prefer Wear OS and I was searching for the smartwatch that uses Wear OS. While doing so on online portals I bumped into this one. I was really curious about this product as this product uses Android 7 and support features similar to smartphones. I did some research on this, went through youtube reviews, it was really impressive. Finally, I decided to get this keeping in mind that I will return it if it won't be up to my expectations. The product was delivered on time even earlier than what it was showing on the delivery status. The packaging was ok. My first impression on this watch was beyond my expectation. It has a metal body and looks strongly built. The screen quality is awesome. Touch responsiveness is super. The battery lasts for a day which is similar to the one I had been using in the past. The watch is using android full version so the capability of the watch to last for a day is good enough. It comes with lots of features viz. camera, heartbeat rate monitor, steps tracker, google play store etc. It has a slot for inserting sim. Users can make and receive calls using it without the need of a phone. However, I have been using it by connecting it with my android phone. Apps will be needed so as to connect it with the phone. It supports most of the android application that we use on our phones or tablets. It has the capability to play youtube and its speaker is loud enough for its size. Overall I am having a great experience with this watch. I am loving it.

I was thinking about getting an apple watch before seeing this and I am glad I waited! This watch is essentially an entire android phone in a watch form factor and also has many watch specific apps. Additionally, the watch contains a heart rate monitor which works great to monitor my heart rate from time to time. Reading through the product description, I can happily say that this watch does everything it says it will do! I would highly recommend this watch!

I never had smart watch before, I am so happy with this watch. At first I want to say, dont need to pay more expensive than this smart watch. Because I can do almost everything like music, weather, health, translate and even camera !there are a lot of features even I haven't used yet. its camera quality is impressive.when I wear my watch, everyone keep asking the features of the smartwatch. Just battery life lasts over a day when I use it normal, thats not bad. its worth. thank you

Battery will only last 12hrs if major functions like GPS are turned off. Also, cell reception is much poorer than my cell phone. Phone function will only work in strong coverage are. Three bars on my phone will only yield one bar on the watch. I suppose this is a result of the watches' smaller antennae area (the wrist band). The vibrator (for notification) is very weak. Gesture function has stopped working but was a big battery drainer in any case. The concept of this phone is good but the phone itself is probably at least two generations from being practical, particularly as a phone replacement.

Finally I don't need to carry a phone when I go running as this watch has an inbuilt phone. I use the SIM card with $5 plan of Speed talk mobile. Its also useful to give to my kid, I can track him and also call him when he's out playing or at a birthday party. I've been using this watch for about a week and battery lasts over a day with normal use. Notifications from my main mobile phone are seamlessly received on the smart watch. The heart rate monitor seemed accurate, there are tons of other features like voice recorder, app installs directly from google play, etc. I installed apps like Find Device, Google music and YouTube. Surprisingly Google maps also work fine on the watch with 4G connection.
