They look great. Installed them 3" from the wall for a sculpted look on the facia. Only thing to note is the sticky tape should not be considered a permanent solution even if they say it is :-) Mine came with screw in brackets in addition so I installed them permanently.
No need for the Pro model unless you need to cut and splice the light strings. I didn't so went with the cheaper Outdoor '2' version. This came with multiple extensions to use between strings if needed.
The adhesive patches on about 6 of the lights let go shortly after being put up. Otherwise I really like the product. Only other suggestion is developing a "splitter" for one string to feed 2 or more other strings from a single point.
DIY the installation, its really straightforward. we love it and our neighbors keep asking where we got it cause its so pretty. love how u can control ur light setting on the phone
These lights are great. They are brighter than I expected. They wash the entire house in color and light. And I never have to hang or pull down Christmas lights again!
