"Effective but..."
I have a big trouble with pet hair as I have 2 dogs and 2 cats. The big sticky buddy picked up hair effectively though the hair soon covered the stickiness. Rinsing it was not as easy as it looks on the TV/video. I had to rinse it through a colander to catch the hair or it would have blocked the drain. I think I need to buy one of those things to put into the bottom of the sink to catch hair and other bits. The smaller sticky buddy was great for removing the clinging pet hair off my sleeves before I did some baking. It was lovely to eat a scone with no hairs to get between my teeth.
