I recently purchased this awesome Pyle Pro 1050 800W battery powered portable PA system for use in the park, on road trips, camping, etc. I also use it in my home.  It has wheels and a handle so you can wheel it all over the place. There is a self-contained rechargable battery so you just plug the thing into the wall and it charges up. Couldn't be easier. I don't use it, but it also includes a wireless microphone.

Just love this thing. Bought from Amazon and no shipping charges!

However, when I got it, the top handle was broken.

Not wanting to ship it back (it weighs 40lbs) I thought to send an email to Pyle Pro themselves (turns out they are based in Brooklyn) and ask if they would just send me a new handle.

And they did! For free! Wow, that's fantastic. It arrived today.

Customer service ain't dead, and they earned a repeat customer!
