Called them, asked if they can install Parrot MKi9100, the owner kindly said that they only have 3100 model but claimed that it is the same thing. Experienced a typical low-ball, they originally offered to install for 150 and later claimed that this is just the labor cost, but i decided to go with it anyways. Installation was quick, no much waiting. Installer was rude. I got yelled at and was refused any cooperation after i just mention that there was a mistake and models are NOT the same. Basically i lost $300 and got yelled at.
