I wanted to buy the FT4 mainly because it was a lot cheaper and had a large number of users giving it good reviews. The more expensive RCX5 would not have generated as many comments as I think a cheaper watch would have attracted more buyers and therefore more likely customer reviews. However, since most of the items Revain sells have a return policy, I decided to take a chance and buy the RCX5. First, the RCX5 has several different screens for the user to choose from while working in whatever sport they play. It worked for me. Honestly, I don't mind that the watch should display BPM, average BPM and time. I emphasize the time display. the smaller polar ones do not seem to show this. I prefer not to wear two watches. This is useful for interval training and was an important feature for me. Also, I'm older and my eyesight isn't what it used to be, and this watch's display is large enough to be seen while exercising. Some other Polar models have readings that are too low. Eventually I bought it so it could be used with both a Bluetooth chest strap (which works well) and a Polar GPS device for more accurate distance readings. Since purchasing the watch I have added GPS and it has worked quite well.
