Yeah the one touch ash cleaner works till it stops working,then it's hell trying to rip it apart and install a new 3 sweep ash thingy,you'll need plenty of bandages and polysporin.
Let's see,the first set lasted 3 years,then i ordered a replcement,they bent and cracked so i installed #%$%^$^&**%$^in the new set and they went bent after a year.
They do work though,quite nicely.
