RONTEN Fitness Tracker, R2 Plus Heart Rate Monitor Waterproof Activity Tracker, Bluetooth Wireless Smart Bracelet with Replacement Strap for Android and iOS Smartphones

Have been using for 3 weeks. Have charged it LITERALLY three times. From box, about 10 days later and about 8 days later, last time was less days because I had it constantly linked via bluetooth to my phone which I find is unnecessary as long as once a day or every other day you remember to manually synch up the data OR you want to use the feature where text and call notices buzz on your wrist and you can control the camara from your wrist; which are GREAT features at this price range. APP is pretty user friendly. Tracks sleep if you choose to leave on. Its water resistant so showering or bathing or swimming are not a problem. The band is a regular watch band which I love but theSlide strap has a little notch to keep it in place wherever on the strap you decide you like it. Straps are also strong enough to STAY ON unless you WANT to remove them to change the color or charge.

It's an attractive, inconspicuous fitness tracker but unfortunately the heart rate monitor, sleep monitor and step tracker are wildly inaccurate. The heart rate monitor is only accurate when the tracker is TIGHT around the wrist, and when you're working out, a tight watch gets uncomfortable quick. I am returning this after a week's worth of wear and am back on the hunt for a more accurate tracker (leaning towards Xiaomi Mi Band 2 - seeing a lot of good reviews on youtube). I purchased this based on all the 5 star reviews on amazon, but I think these people must be using it without caring about accuracy. I'm not looking for perfection, especially from a $30 fitness tracker, but this item is not worth half of that, honestly.

First off, I want to start by saying this is a much cheaper alternative to getting a Fitbit and for me has served the same purpose a more expensive brand would. The band is stylish, comfortable, and works wonderfully out of the box and a full charge. I was skeptical at first because I couldn’t tell if the reviews were legit, but the band has surpassed every expectation so far.I have only had it for a week and will update my review if need be at a later point. The battery lasts a lot longer than I anticipated. After a weeks worth of tracking, many times checking my heart rate and using the gps and fitness modes, the battery is still at 30%. I have checked it more than I will in the future because I was testing the accuracy of the heart rate and steps counted so the battery will probably last even longer. I also have the heart rate on for periodic checks throughout the day. The charging is easy, just make sure you put the correct side in the usb. The touch button on the screen should be on the same side of the usb connector when charging (at least in the us).I find that that heart rate is very accurate each time I checked and the gps and steps counter during fitness modes was on point with my Runtastic app. The VeryFitPro app is average. It gives you exactly what you need but not much more. It syncs up quickly and speaks to the health kit app on iPhone immediately. I did find the steps to be a little off compared to my iPhone pedometer that is built in and realized that the ronten band needs 30 continuous steps before it will save them to your daily total. At first I was a little annoyed by this, but then realized it cuts out “fake” steps being counted from arm movements while I am standing still. I think the threshold for the steps could be decreased from 30 to 15 and maybe the makers will take that into account at the next update.Having said that the step counter has been very accurate when walking or running continuously. The heart rate monitor is always within a couple bpm of my calculation when taken manually with my pulse. The gps is spot on. The alerts are very nice, texts, phone calls, and calendar items come through in the band. The alarm works nice, although the vibration doesn’t always wake me up but you definitely feel it when awake.The sleep tracking is interesting. The app doesn’t give a ton of data and it is impossible to determine how accurate it is but fun to see regardless. I did find that it was accurate when reading that I was restless one night. I would also like to see if the makers could add an REM sleep tracker instead of just light and deep sleep.Overall, this is a steal in terms of the cost and the features it offers. The heart rate and pedometer are accurate and the other features are a bonus. If you are looking to see if a fitness tracker is something you will benefit from or just don’t want to pay the insane amount of money for another brand, then this is the one for you. Order it and you will not be disappointed. (I was skeptical of other reviews as being fake, and I can assure you that I have really purchased this item and I am using it everyday).

It's a really good unit if your looking at fitness trackers at this price. It has the date, day, time, battery level, and connection on the beginning screen. On the Training Mode, it has walk, run, bike, treadmill, hike, workout, basketball, and badminton. It has a heart rate monitor, number of steps and shows calories burned, Bluetooth connection to your smartphone for music and I think your camera; a notice you can turn off or on. I haven't been able to find the sleep tracking on your wrist.The band is a bit big for me, but not uncomfortable. Came with two bands. Battery time is about a week for me. You do have to download the Veryfit 2.0 app; the app does have a sleep pattern tracker on it. I bought it from Amazon and would recommend it.

The step counter did not work properly. I had just walked 2443 step and I had my wife hold my iphone with the app on it. I walked around my kitchen and she watched the iphone and I looked at my wrist where your device was. I walked about twenty steps and the device and iphone counted them correctly. However when I came back to my wife and iphone both the device and iphone reset to 2443.The previous night the device also had stop counting steps, I just thought there might have been some timer because it was late.I was also concerned the the heart rate monitor was too low. At 54 beats per minute, I thought might be a bit low for and out of shape +60 years old man.

Update.I was sent a replacement. The replacement works as expected. In fact, I ordered 3 more as gifts.While I cannot compare with other manufacturers products, I am happy with the purchaseTouch not working at all.Cannot switch between modes. Cannot change the time.Hoping the seller can provide guidance on what the issue is.Is there any film on top that I am supposed to remove? Just checking.

several problems: 1) all trackers have a delay before counting steps, to avoid counting simple hand movements. This one takes it a "step" further. walk 20 steps and nothing is recorded. walk another 20 steps and the number increases and then reverts. Only records steps if you keep moving.I have been awake now for hours and moving around the house but so far only 131 steps.2) pulse. has been as low as 45 and then 140. just tested and recorded 75 with 115 on the tracker. I understand that these are not medical devices but all the same a certain degree of accuracy would be nice.I did like the idea of 2 bands but overall this is not what I was looking for

I like the fitness tracker, but I do question how accurate the step count is. It clocked me as doing over 200 steps whilst I sat and ate my lunch today and claimed I did in excess of 13,000 yesterday when I barely left the house and spent the day doing housework. It does make me more aware of what exercise I'm doing however, and for the price it's a nice item.Update: After a few more days, I have decided to return. Upon closer monitoring the device was recording me doing almost 400 steps walking across our small landing to another bedroom and back.

I bought this tracker a couple of months ago now. I didn't expect a great deal from it but I have been extremely happy. OK, the package was a bit battered that in was in and the manual was stuck together with what appeared water damage. That aside the tracker does everything I want from it. the veryfitpro app downloaded and worked a dream through bluetooth on my phone. Yep cant praise it enough, and it is easy to charge, which I do about once a week maximum twice. Brilliant.

Other half bought lintelek fitness watch which has 4.5 star reviews I bought ronten version with not so good reviews and guess what, both are exactly the same, using the same app etc but with Ronten at nearly half the price. Ronten all the way, people moan on the reviews that it says you’ve done more steps than you’ve actually walked but hey do you really think a sensor in a watch can know exactly how many steps are done especially if you wave your arms about talking. For £15.99 if this breaks in 6months I’m not bothered. Does what it needs to at the fraction of the price

I quite like this tracker. its simple to use which is good as the instructions are useless. it does count steps but only when you are near to your phone which is disappointing as i am on my feet for 9 hours a day at work and cant have my phone on my person so all these steps are missed. The heart rate monitor works well but I don't know if its accurate or not.**EDIT** It only monitors sleep from 11pm onwards. I often go to bed at 8:30pm for a 4:30am get up and it only says I've slept for 5 and a half hours. also if you have a nap during the day, that does show in the results.
