One big improvement from the original transmitters (T31 or T61 transmitters) is that with this model (the Wearlink) you only have to buy a new battery and replace it once they ran out and your transmitter is ready to use again. With the original ones you have to buy a new transmitter every time the battery dies, since the whole structure is sealed. So if your Polar wrist watch came with the T31 or T61, wait until the battery is finished and buy the Wearlink transmitter instead, you will save a lot of money over the years (compare the 39.95 US$ that the T31 or T61 cost vs the cost of a replacement battery).
The other big advantage is that the Wearlink transmitter is more confortable to wear, since it adapts better to the shape of your body since even the electrodes are flexible and are embedded in the fabric. Being flexible and all makes it easier to storage it your pocket when your finish training or if you are traveling.
In summary a great product for your Polar HRM, and a smart improvement if it is time to replace your old transmitter. Dont buy another T31 or T61, buy this one instead.
I run with my Polar six days a week, and probably train about ten hour a week with it. I used to have the T31 with my first Polar (the M61) so I can tell you first hand the Wearlink is far better. In summary more confortable, easier to wash, and a money saver. I was more than happy to trow the old one away after I bought this one.

I bought this transmitter because I did not know that the Polar Heart Rate Monitors came with a transmitter included in the box. I could not find anything that specified this, so I ended up purchasing an extra transmitter.
That being said, this transmitter is super comfortable. The rubber model that comes with the heart rate monitors does not have any comfort issues over this one. The electrodes are sewn inside the fabric of the strap, and they are soft. The only hard piece on this is the plastic transmitter part that is not that big in the front. If you are doing something that involves a lot of body motion, like aerobics, tennis, dance or lifting weights, this fabric model is a better alternative to the rubber model. This fabric strap transmitter might also be a better option for women, who may already be dealing with an underwire bra at the gym.
As far as functionality goes, you wont really need a coded transmitter unless you are using the HRM in a crowded environment where EVERYONE is using monitors. Like at my gym, where the personal trainers sell the Polar brand of HRMs, hold weekly training classes about them, and encourage everyone to buy them. If you dont find yourself in this type of environment, but you find the regular transmitter to be uncomfortable, than this is for you. If the regular transmitter does not hurt you, then you dont really need this.
One problem with this transmitter is the clip mechanism that you use to snap it shut. The little plastic points that clip in look like something I am going to break in about a month. Everytime I snap it open or closed I feel like Im breaking it.
