Product review (2 stars): Poor customer support when product is shipped with problems
I contacted the manufacturer for missing parts as the tower that holds the taps were missing the hardware to mount the tower to the refrigerator. The EdgeStar service technician refused to ship the proper bolting for the installing the product. When I asked them to reimburse me for $7.00 for the stainless steel bolts, nuts and washers that I purchased they  refused, insulted me  and hung up the phone.
The drawings supplied leave a lot of questions and when you ask a question you are referred to a video that insults your intelligence and completely ignores the variations of the different tower arrangements telling you little about the installation process. There are several hardware packages that are included with the refrigerator, some of them are use and some are not. It's up to the customer to guess which ones you use? I just plugged in the refrigerator to see how well it cools but it's too early to tell so far.
Based on my first encounter with this company I found the customer service technicians are rude and of little help. I would stay away from this company and try a company that cares about the product they sell and their customers.
