They are very nice, work hard, and skillful. They really consider the expense for us and figure out the best way to fix the exit door lock. Instead of replacing an expensive new lock, they worked hard to fix the old one. They made it! I strongly recommend them. Only a little bit of a problem with the new keys, which are quite hard to rotate in the lock for opening the door unlike as smooth as the old ones. We are afraid that the rotation problem will make the key broken inside of the lock some days. Anyway, we still really appreciate their friendly patience and hard work. Thank you, brother Rogers!
