I actually never knew there was a Radioshack here until I searched for it online. Now that I know it's there, I can see myself visiting it more often. It's closer to my home than any big box electronics store, the service was friendly, and it was very easy to get in and out of quickly.
Obviously, because of its size, Radioshack probably isn't going to have everything I'm always looking for, but I was very impressed with how much they fit into such a small space without the store feeling cluttered or distracting. It also helped that, as soon as I walked in the door, an employee offered to help me find what I was looking for, and he did. You just don't get that at the bigger chain stores.
