The tracker in itself is quite small and can be well on his pants install yourself in your pocket it will not interfere, I wear it in a mini pocket of my pants. My steps to count very well, and I have to say that the information I so at the end of one day find the equivalent what I really did, if he did not indicate the steps the same time directly, so the display is usually updated after a few seconds. Therefore, there is nothing to complain about here. Also while cycling he takes the leg movement on well.
The software used by Medisana you have to like. It is based online talk, you have to sign up and as soon as the tracker is connected, the data are sent to the Internet that you can love one does not have. I think if you make other devices by Medisana used the sense when you like me has only the Tracker, it's borderline. Advantage is that I can then watch and listen to app on my smartphone the data again. Those who do not need or do not want to send into the network, the data can be downloaded at the manufacturer facilities of the software XNFit Tracker. The Medisana Tracker is identical to XNFit The Clip Activity and Sleep Tracker - pedometer. It is not possible to send the data directly to a smart phone, as the data can only be read via a USB cable. The data is not deleted, so you can use the Medisana and XNFit software parallel.
Of course, the system design is conditioned (connecting and charging contacts are not waterproof) not suitable in order to go swimming or showering, so that not all activities can be covered.
As Schalftracker also works well on the arm, and up to a few times he did not really bother me while sleeping. The carrier is beautifully soft and light weight makes it not noticeable. Only now and then I have remained so hanging on the bedspread.
On the whole, and when one is the restriction of the Tracker aware there is a solid and Tracker for the current price (about 30) well worth the money. Due to the compatibility to a competing product you have the Medisana software not allowed, unless you want to have the data on the smartphone. I hope that the long Tracker keeps me and the contacts are not too quick to give up the ghost.
Who all want to have tracked his activities or want to see the data directly to his Smartphone, but should look at another tracker, but this is not suitable here.
Update:
There is another Tracker is compatible with the Medisana, it is the U3 Fiturbo Wired pedometer Activity and Sleep Tracker, Activity Tracker Plus Sleep Tracker * Black-Green *, the software can also be installed (even without admin rights) and also put online. Unfortunately, I have to fast yet can find no Android app. But the analysis I like visually better than that of the XNFit software or by Medisana.
