I have been cooking on kamados for 18 years, long enough to watch a whole generation of new owners make the same mistake. They buy the cooker, they fight the vents for a month, and then they start buying kamado grill accessories hoping one of them will fix a temperature problem that started somewhere else. The four items in this comparison are the ones I get asked about most, and they are not interchangeable. One is a repair, one is an airflow upgrade, one is an automation tool, and one is an entire second cooker in miniature.

If your kamado already holds temperature and you cook overnight, the controller is the purchase that changes your routine. If your cooker leaks, the gasket is the cheapest fix in this group, and nothing else on this list matters until the seal is right. The table below puts all four side by side, and the sections after it explain which problem each one actually solves.
London Sunshine Ceramic Charcoal BBQ Kamado Grill Smoker, Portable Tabletop Cadet Series (Orange)
Real ceramic in a size you can carry to a tailgate, a balcony, or a campsite
Small firebox means a short fuel load, and it is not a brisket cooker
BBQ gaskets Nomex High Temp Replacement for All Kamado Smokers (Joe, Primo, Grill Dome, King, Komodo, saffire etc)
The least expensive way to restore a seal, and Nomex handles the heat a felt gasket will not
It is an install job and a consumable, and it cannot fix a warped lid or a cracked firebox
Dracarys Round cast Iron fire Grate, BBQ high Heat Charcoal Plate for Large Big Green Egg fire Grate Bottom Grate Grill Parts Charcoal Grate Replacement Parts Big Green Egg l accessories-9inch
Cast iron mass holds heat and survives the firebox better than a thin stock wire grate
Heavy, rusts without care, and it does nothing for a cooker whose stock grate is still intact
SMOBOT WiFi Kamado Grill and Smoker Temperature Controller for Daisy Wheel
Turns an overnight cook into something you can sleep through, with WiFi so you can watch it from bed
Costs more than most of the parts it is controlling, and it only mounts on a daisy wheel top vent

What each of these four actually does
A kamado is a system: ceramic body, ceramic firebox, a metal fire grate, a gasket, a top vent, a bottom vent. Every one of those parts either holds heat or leaks it. The four products here touch four different points in that system, which is why comparing them head to head on price is the wrong exercise. The right question is which point in your system is failing.
The gasket is the seal. The fire grate is the floor of your fuel bed. The controller is an automated hand on the top vent. The tabletop kamado is a separate, smaller version of the whole system. If you are shopping for kamado grill accessories and you cannot say which of those four problems you have, you are about to spend money in the wrong place.
The gasket is the cheapest temperature upgrade
Ask any kamado owner what went wrong first and you will hear the same answer more often than any other: the gasket. That felt strip around the lid is what keeps the seam between dome and base airtight, and when it compresses, peels, or burns away, your temperature control goes with it. You set 250, you walk away, and the cooker drifts because air is sneaking through a gap you cannot see.
The Nomex replacement gasket on this list is aimed at exactly that failure. Nomex is a heat resistant aramid fiber, and the point of it is that it tolerates higher temperatures than the felt strips that come stock on a lot of cookers. The listing names a long run of kamado brands, from Joe to Primo to Grill Dome to Komodo, which tells you the intended use: a universal replacement rather than a brand specific part. That matters, because a lot of gasket kits are cut for one model and fit nothing else.
Two honest caveats. First, this is a job, not a plug in. You are scraping old adhesive off a ceramic rim and seating a new strip evenly, and if you rush it, you will have a leak in a different spot. Second, a gasket is a consumable. You will replace it again eventually, especially if you cook hot and often. If your lid is warped or your firebox is cracked, a new gasket will not save you, and no amount of high temp fiber fixes ceramic geometry.

Cast iron in the firebox
The fire grate is the part everyone forgets until it fails. It sits at the bottom of the firebox and holds your lump charcoal off the floor so air can move up through the fuel. Stock grates are usually thin wire, and thin wire in a 700 degree firebox eventually sags, warps, or burns through. When it does, your airflow pattern changes and your cooker starts behaving differently at the same vent settings you have used for years.
The Dracarys grate is a round cast iron plate sized at 9 inches and listed for the Large Big Green Egg fire grate position. Cast iron brings mass, and mass in the firebox is not a small thing: it holds heat, it resists the warping that kills wire grates, and it tends to keep small pieces of lump from dropping through into the bottom. For long low and slow cooks, a stable fuel bed is a stable temperature.
The trade-offs are real, though. Cast iron is heavy, and you will notice it every time you clean out ash. It will rust if you leave it sitting in a damp firebox through a Savannah summer, so it wants a light oil and a dry home between cooks. And if your stock grate is fine, this is an upgrade you cannot feel. Measure your firebox before you order anything, because a grate that is too large will not seat and one that is too small will rattle and shift.

The controller is for overnight, not for learning
Here is where I have to be honest about my own bias. I believe vent control is 90 percent of kamado cooking, and I believe you should learn to run your top and bottom vents before you automate them. A controller does not teach you heat soak. It does not teach you what a stable dome looks like. If you cannot hold 250 for four hours by hand, a fan and a probe will not make you a better cook, it will just hide the problem until the day the batteries die.
That said, the SMOBOT is the one product in this group that changes what you can actually do. It mounts on a daisy wheel top vent and uses WiFi to hold your set temperature, which means an overnight brisket stops being an all night chair sitting. You get to sleep. You check a graph from bed instead of stumbling outside at 2 a.m. in the rain. For anyone cooking packers, pork butts, or a long plate of beef ribs, that is the difference between doing it twice a year and doing it twice a month.
The catches: it is the most expensive item here by a wide margin, it only fits cookers with a daisy wheel style top vent, and it needs a phone and a network to be useful. It is also, in my experience, the accessory people buy too early. Learn the vents first. Then automate.

A tabletop kamado is a different tool, not a smaller one
The London Sunshine Cadet is a portable ceramic kamado in the tabletop size class, and the word to focus on is portable. This is not a scaled down version of the cooker on your patio. It is a different tool for a different job: two steaks on a weeknight, a batch of wings on a balcony, a campsite dinner, a tailgate where hauling a 200 pound ceramic is not happening.
Ceramic in a small package still does what ceramic does. It holds heat better than a thin steel kettle, it seals, and it runs on lump. The Cadet series is orange, which is a small thing but a real one if it lives on a balcony where you look at it every day.
The trade-off is capacity and fuel life. A small firebox holds a small load of lump, so a long cook is out. You are not fitting a packer brisket in there, and you are not feeding eight people. If you already own a full size kamado, this is the second cooker you use on a Tuesday. If it would be your only cooker, be honest with yourself about how often you cook for two versus how often you cook for a crowd.

Where these four overlap, and where they do not
The gasket and the fire grate are both maintenance items. They exist to restore a cooker that has drifted, and neither one adds capability. The controller adds capability but depends on a cooker that is already sealed and already stable, which means a bad gasket will sabotage it. The tabletop kamado is not a fix for anything. It is a second, smaller cooker.
That dependency chain is the part most buyers miss. A controller on a leaking kamado is a controller fighting a leak. A cast iron grate in a firebox with a cracked bowl is money spent in the wrong place. Fix the seal, then the fuel bed, then automate. If you are buying the tabletop, none of that applies, because you are buying a separate system with its own gasket, its own grate, and its own vent habits to learn.
How I would spend the money, in order
First, diagnose. Light a load of lump, set your vents for 250, and watch the dome for an hour without touching anything. If the temperature wanders or climbs no matter what you do, look at the seal and the lid fit before you look at accessories.
Second, if the seal is the problem, buy the gasket. It is the cheapest item in this comparison and it is the one that most directly buys back temperature control.
Third, if your fire grate is warped, sagging, or burned through, replace it with the cast iron plate. If it is intact, skip it and spend the money on meat.
Fourth, if you cook overnight and you have already learned your vents, the SMOBOT earns its keep. Buy it for the long cooks, not for the short ones.
Fifth, if you want a second cooker for small, fast, portable cooking, the London Sunshine Cadet is the one item here that stands on its own.
The part no accessory fixes
Every product on this list is downstream of technique. The best sealed, best fueled, best automated kamado in the world will still run hot if you leave the bottom vent wide open and walk away, and it will still run cold if you never let the ceramic heat soak before the meat goes on. Accessories shorten the distance between you and a stable cooker. They do not remove the need to understand the cooker.
Buy the gasket if you are leaking. Buy the grate if your fuel bed has failed. Buy the controller if you are losing sleep. Buy the tabletop if you want a second, smaller fire. And learn the vents either way, because that knowledge is the only kamado accessory that never wears out.
