I like this fitness bracelet. This is my second one, and I wear it every day for a couple of years already. I like basically everything about it: starting from the price and finishing by its amazing functionality. The only thing is when I am swimming and want to record my activity - it’s kind of difficult to turn swimming mode off. So I basically never put it in anymore. Everything else works good.

Fair price for fitness band

Xiaomi fitness band is ok, would give it 5 star's if it had comprehensive English instructions, the ones you down load are too brief, you have to discover it's functions by trial and error and basically touch the app and see what pops up and then try and decipher what the graph's and figures actually mean. It seems to be like this for most modern technology these days so it's not alone there. The strap is a nightmare at first but once you've opened and closed it a few times it gets easier. The display is visible in sunlight if you have the brightness on high, steps pretty accurate, sleep monitor ok, only tried freestyle workout that's ok. Is it worth the money? As it has most of the functions of more expensive band's then yes it is. good value

Great budget friendly device!

This fitness tracker has been really great. First off, the battery is amazing. I’ve been using it for nearly a week and it’s sitting at 52%. And I’ve been messing around with it! Trying new watch faces, turning the heart rate monitor to always on, stuff like that. It seems to track steps just fine. Havent had any issues with that.Heart rate seems to be accurate, the only time I had an issue with it was when I was doing pushups. I guess because I was sweating a lot and maybe it was pressed up against my arm weird, it gave me a heart rate reading of 62. I KNOW I was not at 62! I was huffing and puffing!

The only reason I didn’t rate it 5 stars was because the sleep monitoring isn’t super accurate, but again, for the price, I’m kind of okay with that.

Great value product with amazing features
30 December 2019

Overall, I'm really happy with this Fitness Tracker. This tracker is helping me to do 10000+ steps per day and encouraging me to sleep better. Nice to have a watch on my wrist again too instead of using phone. All the features I would want from a smart watch for a fraction of the price. Pros: - Looks great and easy to customise with replacement straps. Wife is very happy with $10 white leather strap we ordered separately. I'm very happy with original strap. - Easy to setup - Accurate step counter - Heart rate monitoring is very useful when exercising and updates quickly. When doing workout, tells you when in Intensive, Aerobic, Anaerobic zones. - LOOOONG lasting battery (over two weeks with constant heart rate and sleep monitoring) - Bright, colourful, responsive ... MoreOverall, I'm really happy with this Fitness Tracker.

She won yesterday lol. - App has great sleep and heart rate analysis that goes into lots of detail and makes recommendations. - Able to set goal of num steps per day and target weight. - Lots of graphs to see your progress over time but not overwhelming. - Handy able to control music, check weather and get notifications on device. - Able to sync with Google Fit Cons: - Display can get easily scratched. - Would recommend getting screen protector.

Most of the praise for this unit is because it is cheap.
1 March 2020

This is a half decent little package, it tells the time and tracks steps well. The battery life is phenomenal, I'm talking well over a weeks usage. You can also get the weather, change songs on your phone and get notifications. The functionality of the watch stops about there though.. The other features of the watch fall short of being reliable... But if that's all your after in a watch, great! This is an affordable option.It's cheap, so you'll forgive it for;- giving an inaccurate heart rate reading,- false sleep quality indication,- alerting you 7 times for one email,- having a strap that is flimsy and unreliable,- a janky charging unit.Unless any of those are deal breakers.. In which case, this watch is not for you.

Reliable & easy to use.
15 December 2021

I'm happy with my purchase. Great value for money. Very easy to use once I found English Instructions on the web. I can't judge accuracy, really just hoping it is so. I really miss the blood pressure reading that I had on my last smart watch - I should have read the description in more detail as this is important to me. I don't use it to it's full potential, just steps & phone & message alerts, so can't comment on all the workout & training modes.

So much, for so little
12 October 2021

Great little tracker. Charge holds for longer then claimed. I love the timer feature and I use it all the time for cooking. Steps are accurate and so is the heart rate. I like that its in color and the face is customizable. The software will give you a warning that it cant be trusted, but I downloaded it anyway with no problems. The band is very hard to latch. This is my only complaint.

The perfect fitness tracker!
25 June 2020

I brought this item last year and has been using it ever since. This has a very unique and compact design. Has AMOLED display which is very bright and colorful and readable under direct sunlight. Has functions to measure hearth rate and step count and it has 6 fitness modes to track your exercise. The most handy feature for me is the swimming tracker. It is very accurate as I have tested it and being a waterproof device is an added advantage on that matter. Battery life is very decent and with average day to day use the battery lasts more than two weeks easily. You can customize the notifications displayed and you can use this device to read your messages, see who are calling you and many other. Overall a very good budget friendly device that everyone can afford.

Well made, bright colors,long battery life. Step count low vs other trackers.
11 November 2020

The fitness band is well made and has up to 20 plus days of battery life depends on settings. There is no stand alone gps which I knew before buying. I compared the MI 4 fitness band to 3 other fitness trackers and the step count is about 60 step count to a 100 count to all the other fitness bands. I have two other fitness bands made by Garmin and one thats an off brand. They all where within a few steps from one another. I bought this band new because of the battery life and I dont need a built in gps tracker. There may be a chance that it may be defective step trackers. Im just reviewing The MI 4 band I bought.

What next for future Mi Bands?
5 September 2022

I replaced my Mi Band 5 that had been very good, but thought it was time for me to upgrade to the Mi Smart Band 7. I was very disappointed with the Band 6. It has improved and more features for me to play with. Early days yet as I have only had the Band 7 for a week. I hope the battery will be better in future, but so far has been disappointing as it chews through the charge very quickly. I hope for improvement by cutting out some of the features, but this should not be the case. I have owned Xiaomi Bands & Mobiles for many years and own a smart scales.
