    Really pleased with my experience buying from

    They provide tremendous value in terms of product knowledge, geographic knowledge and a desire to provide fast and timely service.
    I had my list of must haves and Alex helped me sort through the options very quickly. He provided very timely responses to my questions, he knew which police radar is used in Ontario, and which detector would work best based on my goals. They do the importing so there are no unexpected surprises like customs duties or delays because of missing documents. Buying in our local currency helps as well.

    I’m very pleased with my Uniden R4 purchase.
