I purchased one of these at Costco around September. Assembling it and installing it were very easy except for the water line. No matter what I did it would leak. As for installing it on the wall you can either mount it with screws or with the provided adhesive.
I ended up retuning it to Costco for a refund and the lady who helped me asked "is it that bad?" And then told me that everyone has been returning them.
