Before this i had a bluetooth headset which was OK but a bit fiddily putting on and off. With this you can leave it on all the time as it has a massive 800 hours standby time when u get in your car just press green button and your connected to it. When recieving a call it is easy to answer and is very clear on both ends. If you are a little bit unsure on buying as you have not used one of these before. Don't Be! It took me about 2 mins to get it out the box in my car and paired to my phone.. it couldnt be easier.. Great buy and definately worth £17.99!!!
