SANSI Smart Permanent Outdoor RGB Lights

My wife and I bought these off of Amazon to install year-round, seasonal lighting on the front of our ranch style home and the price point on these was economical.
Quality of the product out of the box seems well constructed and installation was easy with the adhesive backing, but tedious to double back and install all the small screws...many of which fell out of my fingers and got lost in the bedding mulch. Took me three hours to install 5 of the 6 sections of lighting units. (Small screws are a reason for 3-Stars)
The lights are bright, luminous and festive...however, the range of colors appears to be limited. Red, Green, Blue and Violet appear fine. Set has trouble with Yellow and Orange...even when using the preset themes. (This is frustrating and one of the reasons for 3-Stars)
We have not experimented with the White Light feature as home accent lighting yet, so I can not review the functionality of that.
Phone app is relatively straight forward, though a "Help" section would be good for some of the more obscure terminology and advanced functions.
If we can figure out how to get the light units to emit the basic ROYGBV rainbow of colors...including Orange and Yellow...we will be happy to give it 4-Stars.
