I was so happy to use the Handy Assembly Service! It was very affordable and a nice experience. The customer service is on the same level as Wayfair's - top notch. I received an installation date and time shortly after I ordered my chandelier. I was able to change this if it was not convenient. The most wonderful part of this experience was that I was given a time the installer would arrive (not a 4 hour window) and he arrived on the dot! Now that just doesn't happen these days. I was also given his name, picture and phone number.
My installer was very professional. 
After installation I had a minor problem. I called my installer and he was more than willing to return to help me out. (Wayfair told me that if on the slight chance my installer could or would not return, they would have another person help me)
You can not go wrong with Wayfair's assembly service. Thank you , Wayfair. Great job!
