One of the top items this Christmas is going to be the Parrot Minikit Slim Limited Edition. If you need a handsfree speakerphone for your car, this is the one you should get. Granted if you want something that looks a little less girly, don't the limited edition. The other ones are just black, but work just as good. This sleek speakerphone works great in your car. You can easily put it on the visor of your car and forget about it. It easily adapts to your environment and can even easily fit into your pocket. Now, this is so easy to use. As long as your phone as bluetooth, the Parrot will automatically synchronize its phonebook with your mobile phone. Now, it has an awesome text to speech function which allows you to just say who you want to call. You don't even need to train it! If there are several numbers for that person, you just need to specify by saying home, mobile, etc. You can even record a shortcut for your contacts, so you can call them even quicker. I love that it is extremely hard to tell where the microphone is, and it doesn't have any speakers! The sound from this is awesome. The other really cool thing is that you can use up to 5 phones with this, and it has multi speaker voice recognition.
If you know anyone without a bluetooth handsfree speakerphone, you have to buy them this for Christmas. It is so much easier to use than a headset and it looks nice too.
I actually bought this for my brother who is always messing with his phone in the car and never liked the Bluetooth option, and since California recently passed the no hand helds while driving law this was a perfect thing for him, he loves it and says it is a great product.
