Primo Precision Control Kit X-Large

Is this the control kit for a Primo Oval X-Large?

Yes. The X-Large has its own kit, as do the Round, Junior and Large, and the size is written into each listing's title for exactly this reason. Check yours against the title before ordering, since a control kit bought for the wrong grill is not something you can adapt on the patio.

Is a control kit the same thing as a grill thermometer?

No. A thermometer reports the temperature and stops there. A control kit works to keep the temperature where you set it. Both are useful and they are not substitutes, which is why plenty of X-Large owners run a controller for the grill and something like Primo Remote Wireless Grill Thermometer for keeping an eye on the food.

Is it worth it on a grill this size?

It tends to make more sense here than anywhere else in the range. The X-Large is the grill people fill for a crowd, and a full load is a long cook by definition, so it is the size most exposed to a fire that drifts overnight. A controller is aimed squarely at cooks that outlast your attention span.

Will the X-Large kit work on my Oval XX-Large?

Buy the kit that names your grill. This one is listed for the Oval X-Large, and treating a nearby size as close enough is the most common way people end up with a part they cannot use. If you own an XX-Large, shop against that grill specifically rather than assuming the X-Large kit covers it.

Does a controller replace good fire management?

No, it sits on top of it. You still build the fire properly, load enough charcoal for the hours you are planning, and set up the grill for the cook you have in mind. A controller keeps a well-built fire on target; it cannot rescue one that was badly laid or short of fuel to begin with.
