I gave it 4 stars because mine was missing a screw, i had to find my own. and the instructions are not the most clear. Went together quick. very robust and sturdy design, high quality parts. I installed this kit on a 21'' cabinet with a 18'' opening. it fits great! there are spacers that allow for the unit to connect the brackets for a wider cabinet such as i did. this is larger then what is written on the manufactures website and in the description. not the best installation instruction. make sure you put all the screws in the right locations. they are all very similar and instructions are missing labels, but easy to decipher.
