I haven't even been able to try this set yet. First set came with shims all rusted together plus some rust deposits behind the outside cutter teeth. When spending $200 on a dado set you expect the condition to be pristine. Replacement set was sent and had even more rust deposits than the first.Spoke to a foreign based cs agent who said that all they could do is offer a refund on the set. I asked why it wasn't possible to check the replacement set before being sent that it was free of the rust. Didn't get satisfactory response.I'm sure that this set works really nicely per the "FW" review, but don't want to start off with a rusted set and have to buy third party shims.
