The new tab inserts are indeed much sturdier. The original tabs only lasted about a year before 3-4 tabs were broken off. The dealer ended up replacing the entire cup holder (before the tab kit was available). That one also only lasted about a year. After that, they just replaced it using the tab kit (all 6 tabs were replaced), which are still working like a charm after 3 years.

BTW...I believed the kit only come in a set of 6 since there are only 6 tabs in the cup holder.
