I LOVE THIS!!!! My husband got it installed in about 15 minutes. Our house is concrete block and he had no problem with installation! It allows you to select a right side or a left side! It is a led light and I love it. It’s just the right amount of lighting so even in the dark it’s perfect for a night light and also bright enough to where you do not need to turn the actual light on itself to use the bathroom. It also has an outlet at the bottom of it so it’s easier access to plug in curlers, ohone etc. the specifications for measurements are spot on! I like that it has more height than our last cabinet now I can actually store taller medicines lotions etc in it. Shipping was faster than normal. And packaging was perfect no complaints!!! Totally worth it!!
