Semaco Smart Watches, Fitness Tracker Watch with Heart Rate Monitor, Sleep Monitor, Calorie Counter, Pedometer Stop Watch for Kids Women Men (Black)

Blood pressure readings are wildly inaccurate when compared to approved monitors. Even supporting the arm so that the wrist is at heart level doesn't help.Steps readings take into account arm movements so 50 steps gave a reading of over 100 due to sitting at a desk and tidying some papers. When walking I held the arm rigidly at one side and it was still inaccurate to more than 3% over less then 100 steps, and who can walk like that anyway.Estimated calories, if extrapolated from steps, would also be inaccurate.Pulse oximeter seems to be Ok.HR readings sometimes are within 1 or 2 beats compared to better quality heart monitors as long as you stay completely still, but not always. You can't continuously monitor your heart and have to stop and wait a few seconds during activity to get the most accurate reading so it's not useful for sports or fitness. I walked on flat ground and got a reading of 118bpm, by stopping and checking, and then maintining the same pace walked up a steep incline and repeated the measurement. This time I got 63. A 60 beat drop with increased exercise! It's very untrustworthy. At other times it appeared to give better readings. All readings taken on the same hairless piece of skin to avoid confounding results.I had hoped to get a bargain, thinking that the heart monitor, at least, would be useful. However, I did not find the product fit for purpose in any way.

So I didnt expect much for the price if I'm honest and wanted it mainly as a step counter for my husband. It was ridiculously easy to set up via the app, connected instantly and began recording steps, sleep pattern, calories burnt etc. Very pleased with the way it flashes up with who's calling you and also messages you get on phone, even showing you content of the message! Keep bluetooth on and you can see at a glance who is calling u! Battery life seems to be about a week I think... only charged it once since xmas day and didnt charge when opened. Comfy to wear and looks smart too. Husband v happy with it, especially compared to very expensive models, it seems to do the same job! Hope it lasts, and would defo buy another in future.

I looked at how I slept in the morning. This item (god I had to modify the last bit) has no idea. Don't waste your money on any of them. Even if they are £500, not worth it. They are gimics, in my opinion. I will never buy another watch of this ilk.I have had this for watch for a about a year now. It is a novelty. It guesses things from your input stats. The case is corroding (the white specks are corrosion). The button on the side has siezed. I wake up in the morning and I have already done 600 steps (and it's not what you dirty boys are thinking). At my age, sleep is more important.

First of all I'm impressed with battery life. Lasted 6 days!!! I'm having them on all the time, just taking off for a bath, but it says watch is waterproof, but don't wanna try. Is ok to wash hands or dishes, definitely splash proof. Alarm features are handy. Blood pressure measuring is very good, pulse is quite accurate. Not as bulky as Huawei watches, not as expensive as Apple. Worth every penny spent on it. Highly recommend this watch. Because of its features will buy one for my elderly nana.

Nice comfy watch, doesn't cause moisture on skin. Great that does oxygen and bp, pulse. Sleep tracker not that great have insomnia and said I was asleep but was actually just lying in bed. Otherwise good, you don't miss your texts or calls which is great. I used to have very expensive smart watch but changed to Samsung phone so didn't work, this is a fab substitute and much cheaper. Doesn't slide about and lots of adjustments on strap. Not worn in water but ok washing hands.

First impressions great, good price, easy set up and fairly good with notifications. However I am concerned it's not accurate. I've carful set it up, followed the instructions and put in exact height etc, however it seems to be counting a lot more steps then actually walked. I know it won't be dead on, but seems to be really overshooting the steps and distance walked. Watch is linked to my Samsung S10 Plus and running the latest app. Will likely return if can't resolve.

Loved this watch but dont feel the steps were accurately tracked. Walked an hour and tracked 4k steps. Potted about the house and apparently did another 4k. I wish that was true.

I liked this watch for the 12 days it worked. But though it charged just fine before I started using it, and once more after that, it is no longer charging. I tried 2 different outlets and 2 different USB bricks, no luck. And, of course, I threw away the packaging after the first few days of wearing it, once I knew I wanted to keep it. So I assume I can’t return it. I have to check to see if there’s any info about a warranty, but right now, I am not at all happy with this purchase.
