Title: Cheap and works as advertised....
Review: Like my review title says, what more can you ask for? Cheap item that works exactly as advertised? Well...just buy it if you need it.No need to hang those tennis balls from the roof.Pros:1) Reliable2) Durable3) It just plain works.Cons:1) The base connects with two poles with the alert plate/brains on the top pole. The connector for the two poles are not as tight/sturdy as I would like it to be designed.2) I wish the lights blink a little slower when hit and also they put in a few more LED lights to make it more visible in strong light. Blinking and lights up at a slower/longer user controllable interval should help legibility.
