Input: Review_1: I bought this monitor as a newcomer to heart rate monitors. It is easy to use right out of the box and makes working out more enjoyable - you can make sure that you are working hard enough to improve, but not too hard. Very good value., Review_2: It's my first heart rate monitor. Very useful. I always run with it to control my pace. The problem is when I run more then 1 hour because I don't see the seconds as it has only 4 digits on the display., Review_3: Extremely easy to use, only one button. Seems to be fairly accurate. Has a backlight and can beep to warn you if you fall out of a target heart range that is completely programmable. However, the battery is not replaceable and the screen scratches easily., Review_4: I was disapointed to find the booklet with it didn't help with any instructions on use. But after checking the manual on the internet I was able to set it up and use it. It is much easier than others I have purchased. This is what I was looking for. Ease of use., Review_5: This is a good monitor if you have no need for the fancy training models. Beginner or non-competitive runners should stick to basic types like this. The Polar monitors I have had like this are well-made and easy to use and this is no exception. I am coming off a long layoff and plan to use this to work back into shape without risking overtraining., Review_6: If you're looking for just a heart rate monitor (it is waterproof and good for swimming) then this is for you. There aren't any bells and whistles at all. Straight forward, heart rate, time of exercise and that's it. The log only stores your last workouts data, you need to record it before you start another session., Review_7: This was very well-rated on consumer reports. I really like that you can plug in your target heart rate, and it has an audible alert to let you know when you're there. The display is easy to read and it's light-weight., Review_8: I ordered and Polar FT2 and it was confirmed after the order was processed. When I got the email for confirmation, it said FT1. They did the old bait and switch on me! I immediately returned it and very upset with the order after going through a long process of doing research for a HRM. Very dissatisfied!
Output:
This heart rate monitor's easy to use right out of the package. There aren't many features but it does have a backlight, an audible alarm, a programmable heart range and it's waterproof, which all contribute to a great workout. This isn't made for professional athletes, but it's a great option for casual training.
