The internal winding mechanism feels strong and durable. The cord is heavy but still very flexible even in colder temperatures. The case is made of a high impact, hard plastic. The mounting bracket is made of metal and easy to mount to a wall or ceiling. It unwinds and rewinds very smoothly with a constant tension. The mounting bracket will swing from side to side, allowing the cord to be dispensed from a side angle. Ive had this power reel for 3 weeks now and use it daily in a 30 x 40 foot shop. Having 4 receptacles on the end of the cord is very handy when using multiple power tools in the same area.
