Rated 2 out of 5Â by craftybee Only good for 2 years, at best
I received this a couple of years ago as a gift and it worked with only a few hiccups the first 1.5 years. Since then, it has been one problem after another. First, the buttons stopped working. After a few days, they started working again, except one (top right), and the action of each button changed. I could still manage to get my workout done until a few months ago when my heart rate randomly stopped registering for minutes at a time until it wouldn't register at all. I replaced the battery and now it only registers very intermittenly so I no longer have an accurate calorie count. Not happy at all, especially since I stayed with Polar over another brand.
Rated 1 out of 5Â by SRF1 Like others have written this is my second FT 4. Happy with the first one. The second has been problems after the first year or so. Changed batteries a couple of time. I hand wash it in the sink after every use and occasionally wash it in the machine tied up in a sock. The display jumps around. This the most consistent thing about it. I use it in town and out in the mountains when mountain biking. Don't think it is outside interference. Best place to use with gym equipment. Last one for me. as a matter of fact I am looking for something that serves my purpose. That works.
Rated 3 out of 5Â by Minty Good basic tracker
I've had this for almost 2 years and it's served me well. The basic Heart rate monitoring and calorie tracking work great, and the strap fits well. I did find it comes undone occasionally while running if I haven't been careful while putting it on, and it may need to put on one way up for best grip. I'm finding that it is developing a sharp spot on the plastic connector just recently.
My biggest dissappointment is in the WebSync - FT4 doesn't come with an uploading connector. Also, the free App you can get doesn't work on any of my Android devices. So I am stuck with the watch only, and no further info from uploading the data to my computer.
