I had been locked out of my house for a couple hours hoping to figure out how to break in or get in touch with a friend who had a spare key, but had no luck. Roy arrived shortly after I called and was nice, professional, and quick. I was back in my house within 30 seconds of him arriving. Highly recommend.
Lior was extremely helpful when I called him, and though he didn't end up coming to help because he was on another job, he talked me through the best way to find another locksmith, and checked in about an hour later to make sure I had gotten into my apartment. I was very impressed with his assistance and professionalism and would not hesitate to call him again.
Called to get our locks replaced after moving into a new apartment. Lior was able to fit us in that day and came prepared with all of his equipment. He was extremely professional and friendly, and installed new locks in 45 minutes. I highly recommend.
