AK1980 Waterproof Fitness Tracker with Heart Rater Monitor Activity Tracker (2017 Version)

I bought this fitness tracker after having a fitbit flex and both of my changable bracelets broke. The bracelet seems to be well made, it has a step tracker, blood pressure monitor, heart rate monitor, shows how many calories you've burned as well as a sleep monitor! It's awesome. The step tracker is accurate unlike the fit bit flex that counted all movements and gave skewed step totals. I don't have any heart or blood pressure health concerns but for the price I thought they were cool features to have. I recommended to a few friends just for those features alone! So far so good. The shipping was fast, packaging sufficient and the instructions for set-up were easy to follow!

Finding a tracker that does what I want was not easy and I ended up with this one. These trackers do way more than most people want, i.e., all kinds of notifications.. I just wanted to track steps, distance, time. This model also takes your blood pressure, but don't trust it. I am tracking my BP constantly due to a health issue, and I have a BP cuff at home. The tracker constantly says my BP is 20-30 pts below what my home cuff says or the doctor's office says. Not trustworthy. I am also having trouble charging it. It charged fine the first time but since then, it doesn't charge properly or fully. It also, on it's own, decided to reset and it came up with a different date and time. Took me getting the instructions out and fussing with it for over an hour to get it to correct itself. When it is working properly, it does the steps, distance, and time okay. When it craps out, which I'm pretty sure it will, I will not buy another one.Update: It's been a few weeks since I posted the above review. About a week ago, the tracker died. Just died. It had been working pretty well for the few days prior to it's death, although it had reset itself, randomly, a couple of times. I took it off before bed, as usual, and it was working fine. The next morning it was dead. Plugging it in to the charger, didn't do anything. Again, I wouldn't recommend buying this.

The best customer service possible when I had problems with new "Tracker". Immediate replacement, no questions asked and virtually overnight. Subsequent questions were immediately answered. I have some serious concerns about the Tracker, the APP, and accuracy of the BP monitoring. The Sleep Tracker is inaccurate and frequently misses "awake times". The BP monitor cannot be relied on for accuracy and should not be used for "real time" readings if you have a BP problem. The heart rate monitor is accurate, but had shown me to be "clinically dead" with no heartbeat in the middle of intense exercise. The APP is "bare bones" but I like it. User's Manual is incomplete and poorly written. It leaves many questions unanswered, which customer service gladly answers. I am still adjusting wearing positions and tightness of band to try to eliminate a "0 heartbeat" during exercise and other inaccuracies and inconsistencies. The Step Counter is consistent. These are "great people" to deal with and VERY COURTEOUS! I rate “customer service” a full 5 stars; the Tracker itself is below average so far, but I am reserving a "final verdict". After about a year of use, my initial reviews stand. Customer Service 5 Stars; the Tracker itself 2.5 Stars. Only the basic functions of heart rate and step counter are accurate, consistent, and dependable. My Tracker still will occasionally show me to be clinically dead, with no heartbeat during exercise.

Overall, a nice watch. I didn't have any issues with bluetooth connectivity and the phone app was decent. However, the watch's touch button is quite sensitive to water pressure while you're swimming. This will cause the watch to cycle through its different modes (running, distance, sleep etc.) In my experience, the watch ended up in "Clear data" mode and automatically erased data just by swimming. Discussed with vendor, and unfortunately, there's really nothing that can be done.

Mine came with no charging cord, so I left a 1-star review and the company immediately contacted me and sent me another one at no charge to me (didn't make me return the original one either). So that was really nice and good customer service is hard to find these days.The fitness tracker itself is decent. Fits nicely and everything works fairly well on it, but I wouldn't trust the blood pressure monitor as a BP tracker. It's just to give you a general idea where you're at. The sleep feature is interesting, when it works. It didn't record anything for me last night, but maybe I did something wrong.Overall a decent fitness tracker on par with the bigger more pricier brands. Works well for what I need it to do. The app was easy to find and download, and it recognized my tracker immediately. Certainly not a bad little fitness tracker and I would recommend it.

Have been wearing this for about a week, sort of does what it suppose to but I have a hard time linking up to my phone in the morning. I have to reset my phone a couple of times to connect. Everything is in and working but not connected. I just use to monitor my BP and heart rate, not exactly on spot but gives me idea what is going on.UPDATE: I had this item for about 10 days worked good until today. No info from tracker to app is being sent. No sleep, no HR, not reading my HR in the hour like suppose too. Can't get on to web site, non UPDATE: the sleep mode has not recorded my data for two nights now. Everything else seems to work.
