Map Troika used for travel in the Moscow transport. Troika costs 50 rubles, and it is possible to recover, to get back its cost. Keyring Troika costs 350 rubles, you can not return it, and at first glance it does not have sense, but when you start to use it found three global benefits.
1. While I enjoyed the card several times, I forgot her leaving home. Once I had to buy another one, put to 60 trips and spend it, and then return to the main map. Keychain hanging on keys and forget it, leaving the house is almost impossible.
2. Three bind to the personal account and the owner did not do (though long promised) and I am always afraid of losing the card. Lose Keychain succeed only with the keys.
3. When find is three, when you walk in the subway and I'm not just trying to pay the fare driver's license in the pocket are a few credit cards, license and Troika hard to the touch. :) When the Troika as a keychain, so there is no problem - just find the keys in his pocket.
I use the remote control for two years now and it's really very convenient.
