After nine months of having two Solatubes installed, I could not be happier. The installation was great, the service very professional and friendly. The transformation to the living room and guest bathroom is wonderful. Both rooms went from caves to light filled rooms. We often do not have to turn on a light in either space until near sunset. Guests try to turn the lights off in the bathroom, just to realize its the tube. The tubes even gather light from the street light outside at night. So we have dim nightlights in both rooms free of charge. One thing I daily smile at are the rainbows case by the Optiview Diffuser in the guest bath. There is just something cheerful about the colorful beams of lights. When we remodel the kitchen and in any future house we buy, we intend to install more Solatubes. They have been our best home improvement investment to date.
