Query: AMAZING but the handle slides off

I have a rottweiler that seasonally sheds 365 days a year!! It is nonstop! This thing will take off so much hair with one sweep it's insane..and it will just keep going and going until we are sick of doing it! Yeah, after each time you have to pull the hair out and throw it to the side but I think you have to do that with ANY brush, especially one that grabs this much hair so easily!My only complaint is that after plenty of use the handle has now started to slide off but it still works just the same. This will last many years to come as the quality of the blades themselves is very high.
