Title: I love my SI monitors!
Review: I own the ECG5, 7, and 9 and love them all! I did receive my last one with a dead battery, but that really wasn't a big deal to me--a quick trip to my local jewelers and I was set to go. I also own a Polar F6 and have to say that the SI monitors are far superior. The chest strap is much more comfortable and the monitors themselves have a lot more functionality and are easier to program than the F6, in my opinion. My favorite SI monitor is the 5 as I like the lap data capture better on this one than the 7 and 9. I wish the other reviewers would have commented more on the features instead of mainly their feelings about the batteries.
