Question: What is the size of each blade?
Document: Just be in the mood to do it. Make the time and have patience. Easy does it. A magnetized screwdriver head, good aim and a steady hand also help. Personally, I found mounting the brackets to the blades a bit tedious but, overall, an easy installation. It looks terrific on the ceiling. Despite of its small size, those blades put out a very nice breeze and the lights are just perfect (2 40-watts bulbs).
1st off this fan arrived VERY quickly of which I was pleasantly surprised. After reading the other review regarding assembly I read thru the instructions carefully. To no avail, the fan blade assembly was insane. The light fixture is pre-torqued / wired into the fan motor so you have to painfully access each blades screws thru a small porthole into the motor will a long handle screwdriver as if you were performing surgery. Dropping screws and walking up and down your ladder is unavoidable.
love this fan.. awesome colors,  good quality. will buy this product again. looks really nice in my sons bedroom. worth the money
love the look, but not the easiest to install. i just installed 7 fans in my new house and this was the hardest by far
This product works very well. The fan moves a lot of air for such a small fan. My son loves it.
This fan is VERY cute & with 2 people working on it it was a breeze to assemble & install. Unfortunately it doesn't move enough air for our needs so we're returning it. If you need a slight breeze this fan is for you. If you need it to actually move lots of air to cool a room you'll be disappointed.
The fan arrived last week, 2 days after I placed my order, but didn't get to install it until this past weekend. Although I had to reinforce the ceiling light fixture to properly handle the weight of the fan (a major ordeal which took just about al morning! ), the installation of the fan proper was relatively easy. Prior to purchasing it, I read about the difficulty of fastening the blades to the body of the fan. It was not so bad.
Quite slick and colourful. Terrific price. The boys love it.
Perfect ceiling fan for child's room. Nice pop of color and illuminates room nicely. Very happy with this purchase and Amazon delivery can't be beat!
Nevertheless, once I finished it worked like a charm. Fan is nice and puts out good airflow. I'm pleased overall.
