I would probably use them again.
They came out to trim a mesquite tree in the front yard. Communication was excellent (we texted). The price was pretty comparable to many other quotes I'd gotten. The reason I went with Moar was that it seemed they seemed to care a bit more about my small job than some of the others I had gotten quotes from.
They showed up on a Sunday when they said they were going to and finished the main job. I would have given them five stars but they turned my one day job into a two day job when they had to come back to finish the clean up.
Overall: Reasonable prices, great communication and very reliable. I would strongly consider using them in the future.
