Fire-Boltt INVINCIBLE 1.39" (3.53cm) AMOLED 454x454 Bluetooth Calling Smartwatch ALWAYS ON, 100 Sports Modes, 100 Inbuilt Watch Faces & 8GB Storage

Delivered today and used for 3 to 4 hours - I initially bought Noise colorfit assist 3 and returned because of connectivity issues.. And refunded now bought This one as it was meeting my all requirements under my budget,, but there were reviews which are scary.. But after using it I am relieved.. People saying it's used and scratches on Back of watch.. Actually you have mistaken.. It get little scratch because of company packaging.. I little touch of watch strips makes some lines on watch but if you rub it with soft cloth it goes off... No need to worry it's always brand new watch.. This devise is working as expected and as per the specificationa provided.. Devise connected easily and hasstle free call receive and talk.. And even you can use mobile photo talk which you get option in phone and I don't check all sport modes.. But Heart rate was very accurate.. And lot of watch faces and amoled Screen just wow... Ultimate clarity batter than any mobile.. Just 40persent brightness it's very bright.. Outdoor also very clear... So much options.. Notifications also works well.. Very satisfied.. thank You Amazon and Firebolt... Need screenguard and software upgrading system in coming days.. Only disappoinment is Alexa and GPS is not there... But I don't require that..

The smart watch is really good, speaker sound is in good quality, also amoled screen is excellent, touch screen is really good. This watch can be connected via Bluetooth through app or can be directly connect to smartphone. Only problem I noticed is there is no call log option, if it is there it's good to make a call in the watch itself. One more issue is if u connect bluetooth without headphones all media sound will come in watch speaker directly. If you connect both watch n head phone via Bluetooth, the media can connect in headphones. If media is coming in phone itself without the help of headphones, it will b good, any way watch built quality is good.

Watch seems very nice overall but I'm returning due to following issues.1. Contact list is not in alphabetical order.2. There's no separate option for vibrate and ring. So, watch always ring and vibrate when there's call.3. Notification is popping up invariably.4. I need to sync Contacts each time when I connect.5. I always need to click to operate all features.Otherwise, Battery life is great, that's 2 days, touch is amazing, bluetooth calling is excellent to talk directly from watch, always on feature is great to just see analogue type watch with day and month,(Not whole watch face will remain always On).

The media could not be loaded.  Capturing heart beats for my sofa. Strange.

This is budget smartwatch so better call it a wrist band.Good things-Budget watchGreat displayGood storageSpo2, BP, Heart rate, step countsConsWatch faces are limited and not upto mark.Bluetooth is directly connected to phone so all sound will come from watch so it becomes annoying at times.Bluetooth connectivity issue will be there. I think it's not more than 5-6 meter.Cannot customise watch face.Cannot silent the phone by watch.Accuracy of the health parameters is not upto mark.More is needed yet to be discovered but in nutshell it's just an wrist band and this is what the Boltt also says.

The watch is good in the key features..The sound, the music and the mic all works very well...Its calling feature also worksThere is a number of sports mode available too...Battery backup, sensors all work great...But the app does not have a gud gui and does not have many featuresAlso they should have added a gps feature for the price..Also custom watch faces feature would have been also greatOverall good for the money but could have gotten better

Concerning issues with the item received:1. The sensor at the back of the watch has cracks and scratches. Protective film on the sensors was missing.2. The mic is not functioning.3. The sound from watch distorts.Belts and dials/screen are in good condition.

The media could not be loaded.  Before anything else, the App to work with is called FITWINNER (am using it on iOS).Now to initial experience sharing -Overall pretty impressive BUT -the Device seemed to be used as it has scratch marks (lots) at the back panel over the charging port.Also the Charging cable seems to slide off the watch pretty easily (magnet not impressive).And this Display getting illuminated on its own gave a feeling that it might be a damaged unit. However a Device Restart from the AppOn the positive side -Gr8 big Amoled with deep inky blacks.Plethora of watch faces in built and more available on App.Rest...yet to test..Critical Flaws I noted after a few weeks of usage [ the first unit was faulty and had to replaced ] -1. The first unit display kept going all white out on it's own2. The replacement unit keeps restarting on its own sometimes. No idea why !3. Being a biker myself,I wear riding gears, and this watch particularly doesn't feel very comfy. I have smartwatch from other brands and they don't.4. Highly inconsistent "Raise to Wake" feature !5. Accidental touches while you're doing something would take the watch into some diff menu page sometimes.
