I live in Seattle and was in Toronto on vacation. I dropped my Samsung S4 and my screen went out. Was looking at a couple of places and mentioned this one to my cousin and he said, "oh yeah...they are very good". So I took the subway down to Techknow and I wasn't disappointed. They had the parts, were able to repair it and they did it in an hour. Fast, friendly, a fair price and great service. If you need smartphone repairs..these are the people to go to, Thank you so much.
