Karadar service

I have ordered a model SG565 at R3000 from this company and they delivered a cheap model E8 speed camera detection unit. This item can be ordered online from many companies at R400. The main issue with the Karardar company is that they do not list and contact cell number or address on their website and they have only responded once to my 10 emails to them. Karadar is expensive, unreponsive and unreliable. Do not buy any items from them you will be taken for a ride. The E8 item reviews on the internet indicates a useless device. Do noit buy it. Their customer service is useless.
