Simply put, especially do not buy it! You will do a certain economy.
I bought 3 Wistiki Noel last (not having had the chance to have experience feedback)
Now five months later, no one works! I sent an email to SAV and 0 answers ...

I went into account the day having lost my keys, I was proud to tell me I can finally use Wistiki but it never worked. But the key was in my apartment.
Then, I wanted to check the status of my second key ring it did not work either ... and having wanted to change the battery (even if the problem was not the) key the door is started ringing without possible end of the stop.

Last thing you can not put it to an existing key ring except an old cable hanging down.

I do not know if any other product on the market but this one deserves to be in any case buy
