Query: DO NOT BUY the non-TX model - it WILL fail, & Cuisinart will NOT honor warranty.

Two things about this item:1. Avoid buying discs with model numbers that do not end in "TX". Cuisinart puts out two versions of its discs, the TX and non-TX. With the exception of "TX" at the end of the part number, the part numbers are the same and the discs look superficially identical. BUT, the non-TX have weaker locks where it fits on the stem. Mine failed after 2 months of moderate use - the disc flies off the stem as soon as you start using it.2. Cuisinart will only honor warranty for accessories purchased directly from them! I think it's ridiculous and should be illegal, but that's their official policy.Bottom line: spend a little more to buy the TX version of this disc directly from Cuisinart, which has a stronger attachment mechanism and is covered by warranty.
