What's there to say bad about this tracker? Nothing!! I have owned several Fitbits over the last several years. They work just fine. But they don't last forever. So every time you have to replace one, it cost a little bit more money. So I was going to replace my old tracker that was falling apart with a Fitbit Charge 3, but I was reluctant to pay $149.95. I decided to look around at other trackers and I came across the Lintelek IP67 Fitness Tracker.I was a little skeptical because the price was only $28.98. But, after reading quite a few reviews, I became intrigued. After 1,392 reviews and a 4.0 feedback rating, I was convinced to give it a try. After all, the Fitbit Charge 3 had only 3.2 rating with over 2,000 reviews. What was really a turnoff was that 32% of the feedbacks were rated a "1", compared to Lintelek IP67, which only had 11% "1" feedback rating. So, I decided to give it a try.I ordered the IP67 Tracker on Feb. 6 and received it Feb.8. After looking it over, it appeared to be constructed very well. The manual was easy to read, and after charging my new tracker and downloading the VeryFitPro app, I connected the tracker easily to my iPhone 10XRS through bluetooth.On the basic setup, the watch has 6 different display windows. The first is time, date, available power & the Bluetooth connection. Next is total steps, then pulse rate measurement. After that, there are separate windows for timed walking, timed running and timed biking. If you add an alarm, a 7th window is added.If, for instance you use the tracker while you are running, you can access all kinds of exercise data about your workout. If you tap on the touch key, you'll flip through heart rate, step count, calories burned, distance, measured pace, average pace and exercise time. After you finish the exercise, you'll see displayed total steps, calories burned and average pace and BPM.The app is quite informative. It will display your steps for the day, activities that you accomplished, calories burned, distance and active duration. It tracks your sleep patterns, too. It displays your deep sleep time, light sleep time and wake time. You also set your alarm on the app. There are so many other things that you can obtain from the app, but I only highlighted some of the more popular uses.Charging is a breeze. If you look at the pictures I submitted, you'll see how easy it is to charge. It's so much simpler than the Fitbit process. All you do is remove one side of the strap which reveals a USB connector. Plug it into a USB receptacle and a red light comes on to indicate that the tracker is charging. Once charged fully, the tracker can last up to a week or more.All in all, I would say that this tracker is well worth the money. I can get as much information from the Lintelek IP67 as I could from my Fitbit trackers. The price, for sure, is a deal breaker. The only thing that I would improve on is that it would be compatible with more apps such as MyFitnessPal and MapMyWalk.
