OPTA SB-136 Diotima Bluetooth Fitness ECG Watch| Blood Pressure Multi-Sport Mode| Heart Rate | Waterproof |1.2 Inch Color Screen Fitness Tracker for All Android/iOS, Medium (Black)

When I received the watch its Look and feel is premium I was happy and delighted with the product.This watch I found what I was looking for, but it was an illusion which ended in 7-8 hrs when I actually used this.Information and claim made by the company is inaccurate and false, dont buy this watch.I received this watch yesterday afternoon and wore it in the night at around 9 PM and would have slept by around 11 PM. When I woke up at 4.50 AM there was no sleep records in the watch I tried the same with the App as well but there was no data.And for my surprise step count was having 100+ steps.When the basic feature of Smart Watch is not accurate or not able to calculate what could be expected with the ECG, BP and Heart Rate.ECG it's just showing the graph, which is of no use to people like me who dont have any understanding of ECG graph.Now today on 3rd Day, Please find below the detail review point to point1. Sleep Detection - It starts detecting after 10 mins when u wake up, so just wait for the result after couple of minutes.2. Pedometer - It's definitely not accurate as even during sleep it shows 100+ steps, or might be I don't understand.3. BP - It's giving an option in App to calibrate the BP by measuring with some other Device which u feel is accurate and it will calibrate its measurement to that device, I didn't tried this option, if it's working then it's an wonderful device.4. SPO2 - For me it's looks accurate.5. Heart Rate - I felt this is not accurate as it's goes down 60 as well, and for me it's always 80+6. When you are using this Device in Sports Mode it will calculate your Steps and workout in that Mode and it will not Sync to the Total Steps and Exercise.7. It's App is having some issues as in reports summary it won't reflect the Summary of Blood Oxygen Report and BP Report which you are measuring it form the same device.So my first hand experience with the watch is not good and I would request others not to buy.Note : For Company who is selling this product need to be attentive on the Review of Customer or they May connect to Customers if they really want to establish their Brand or Products.

Very few features to play with and readings not so accurate.

As advertised, received today in good condition. Readings are accurate enough. Overall satisfied. Could improve user manual though
