Review: Best health and fitness gadget I have purchased in a very long time - The Mi Band 4 was recommended to me by my cousin and after allot of research and comparisons of this with other trackers, I opted for this one and very pleased that I did. I wanted something that had the functionality to show stop watch counts, steps, heart rate and activity pace all at the same time and this does exactly that, however other fitness trackers dont have the functionality of a stopwatch or the function to use a stopwatch with a heart rate monitor. Overall plus points: - The step counter is very accurate when used in walking mode, however I don't think the standard step counter is accurate. - The heart rate monitor appears to work fine, however I will compare it to the heart rate monitors at my local gyms treadmill, once the fitness sector is given a Covid-19 green light to reopen. - There is a calorie counter that compares burnt calories to food types such as 4.7 bottles of coke, which is really interesting. - I dont know how Mi have managed to design a tracker with a very long battery life. I had a Sony fitness watch that only lasted 2 days. - You can use the watch for days and it records all of the data without you having to sync with a mobile device via Bluetooth. - The workout data shows your average heart rate on the mobile app, which is brilliant. Overall negatives: - You have not purchased one! I won't be able to comment on the trackers other features as they are not relevant to why I purchased the device, however from what I have gone through, they all appear to work fine, such as the weather app and so fourth. If you are someone such as myself that appreciates gadgets and tech of excellent quality, then you will understand what I mean if you own one of these trackers. I am very impressed with this device that I am even tempted to buy a 2nd tracker as a backup. Overall if you are looking for a fitness tracker with the same reasons as myself, please go ahead purchase it. You won't be disappointed and I hope you find it as valuable and useful as I have.
Review: Good purchase 👍 - I have been using Mi band since it's first appearance in the market. Recently thought of upgrading it, so ordered a new one on desertcart. First impression of the product is quite satisfying. Yesterday I received Mi band 4 in my hand. I was quite excited to wear it. Now for desertcart delivery, it's absolutely great. Received the package before it's delivery date. Packaging was, I think sufficient. Mi band 4 box was sealed. The box contained the following: ->Mi tracker ->rubber wrist band ->USB charging cable and a guide. The first thing I did was to remove the tracker from the band and put it on charge through the USB charger. It took around 2 hours to get fully charged. When it was charged fully it vibrated to notify of its status I really liked this part. Then I paired it with my Mi Fit app. In app: First -> my old band was deactivated. Then pairing with the new one started. After successful completion of pairing, it got another firmware update. After that my Mi band was ready to use. Now my Mi band 4 is up and running. No issues till now. Look n feel: Mi band 4 has a pretty good amoled display. Touch is working fine. Step count and heart rate are almost accurate. Other features I didn't check. You can control a lot of things through it. You can directly adjust brightness through the settings. Keeping brightness low will help battery life - I guess. It has three display theme. I like the default one. Battery life: As I have just started using it, I can't say much about it. Price: In this price you can't expect much. It's worth buying. Original or not: I am not an expert on this. But before buying I researched a bit about the product. I noted some points and decided to check those upon it's arrival. Those are: 1. Mi band 4 box top right corner mi logo : bright orange ✅ 2. Holo graphic 4 at the front of the box ✅ 3. At rear of the box bar code sticker✅ 4. Mi encryption on USB charger cap✅ 5. Mi encryption and serial number on Mi tracking device✅ 6. The guide book✅ - All were checked and in place. Now only thing is to see how it performs in long run.

## Questions & Answers

**Q: Seller! Is this the global version of band? Is it genuine?**
A: Not seller, bought this watch. It is a scam then are sending out cheap fakes. Please avoid and report.

**Q: does the band track daily calorie burn/TDEE?**
A: I'm sorry, I don't know the answer. I bought it for my daughter. Maybe google the item.

**Q: Have blood pressure?**
A: No, only heart rate

**Q: I want to buy one for my wife, but she doesn't have a smart phone. Would it work at all? Or would it work via my smart phone?**
A: I am not 100% sure, but what the smart phone does is that if you download the Mi Fit app, then you can sync the fitness tracker with the phone and have all the data available on the phone as well. Other than that, you can use the fitness tracker without the phone.

### ⭐⭐⭐⭐⭐ A feature-rich – affordable – lightweight and efficient smart band!
*by M***K on 8 August 2020*

I bought this watch NOT because I needed a fitness tracker or heart rate monitor, but out of curiosity. Now that the market is dominated by the famous Apple Watch, Samsung Watch, Garmin etc. which have a more painful price – Xiaomi Mi Band 4 caught my attention through its features at such an affordable price. So, I decided to give it a try. You can easily see the time and date, step count, battery life, messages, caller ID, and other notifications coming from your Bluetooth-paired phone - on the colourful and bright OLED display. · One feature that I really like is the customisable watch faces you can download. There are tons of customisable watch faces on the internet. The combination of colourful watch face options combined with the vivid AMOLED display just adds to the premium feel of the Mi Band 4. · It's extremely comfortable to wear and not at all bulky - you truly do almost forget that you even have it on. · Build is durable. I've accidentally knocked the face on various surfaces, and it still doesn't have a scratch. The band seems to be holding well against daily wear and tear, so far. · The heart rate is near perfect accuracy most of the time as I've compared to manually checking my heart rate. · The battery life is fantastic. I haven't charged it in almost 10 days and it's at 41%. NOTE: the battery life will depend on the settings you've chosen. 👉 The Alarm + Custom vibration patterns are my favourite features of this band. No more annoying alarm sounds in the morning for me. Just set up a time and frequency - and this band will gently wake you up with a vibration at the scheduled time. ⓘ Mi Fit -> Profile -> Mi Smart Band 4 -> Alarm -> Vibration And then you can add a custom pattern for your alarms or apps notifications. ✔ Pros: + Comfortable and lightweight to wear + Water resistant (up to 50m) + Heart rate monitoring + Automatic activity tracking + Incredible battery life + Bright and colourful AMOLED display + Customisable watch faces ✖ Cons: - No Auto Brightness. Brightness control from within the band menu is a useful feature that helps you save / optimize battery. It would be nice if they had implemented an automatic brightness by using a brightness/lumen sensor but that's probably a feature for future iterations of this band. Overall, I would recommend to any of my friends looking for an affordable fitness tracker. ↘ ↘ ↘ I rely on reviews when I make purchases, so I put a lot of time into reviewing everything I buy on Amazon.
