I purchased a used Kamado Joe classic 2 several years ago and the person had a jotisserie and a basket for it too that I purchased along with the smoker. I have done whole chickens, Al Pastor for Tacos, and turkey breasts.
I love the way the meats crisp up and get the slight charring that really adds flavor and visual appeal to your cooks.
I liked the jotisserie so much, I got one for the used 24" Kamado Joe Big Joe i recently purchase. I'm looking forward to cooking a full size turkey for thanksgiving. The spit looks big enough to cook 2-3 whole chickens at once. It may seem a little pricey at first but it is built well, and the quality of food that you'll produce is well worth the cost. Look for a video on YouTube for Al Pastor and you'll be hooked!

This thing is a must for your Lg BGE fits perfect seals tight, just an excellent add on!

I don't have a kamado joe (I have a similar kamado style smoker from Vision), but this works great! The rotisserie works very well, and there is minimal smoke/heat loss. Highly recommend.

So far very happy

I bought this for my Weber Summit Charcoal Kamodo with the intention of modifying it down the road (cheaper at Warehouse prices since I'm going to be invalidating the warranty).

Out of the box, it actually works acceptably well even though it does *not* fit as intended. Without modification, the inner lip of the JoeTisserie hits the inner lip of the weber bowl at the rear. I've used this a few times as-is without obvious issues. Even though it doesn't sit right, it seems plenty stable and there aren't huge air gaps, so temperature control doesn't appear to be particularly more of an issue than when this is set up on ceramic grills (I believe these setups are inherently less airtight with the spit rod and extra surfaces, so maintaining really low temps would be difficult even when fit as intended to a Big Joe, tho that's generally not needed for rotisserie IMO).

It *is* possible to modify this product to fit properly if you're handy. Though I haven't yet attempted this, I know someone else has done this successfully, and, having studied it, I have a good idea of what's required. Kamado Joe's Big Joe and probably most other comparably sized ceramic kamados are at least a half-inch deeper (especially at the back) from the plane from which JoeTisserie hangs. Measured from the bottom of the outer lip, which it hangs on the ring of the grill, the inner lip projects about 1.75 inches down at the back whereas the Weber only has about 1.5 inches of clearance here before it hits the bottom (basically Weber's built in firebowl).

In other words, you need to remove a little more than a quarter-inch of metal from the inner lip at the very back, progressively less as you work towards the front (only about 1/4 near the rear needs to be touched due to the way the JoeTisserie is angled to fit the hinged lids). The seal, such as it is, is entirely created with the outer lip, so the evenness of the modifications on the inner lip shouldn't matter much, if at all. The point is to obtain enough clearance so the outer lip can sit flush on the Weber (obviously, taking care to sand and touch up with high temp paint for a more professional-looking result, not to mention avoiding creating an abrasive or potentially finger cutting surface).

Before I saw it, I initially envisioned a more complex task so I thought I'd share this for the benefit of others interested. I was also pleasantly surprised that this isn't strictly necessary, i.e., it works OK out of the box, though I plan on making this change in a few days (mostly aesthetic + perhaps some small performance advantage).

Edit: I modified this to fit my 24" Weber kamodo-style grill with a standard Dremel rotary tool and a few cutting disks. As expected, it wasn't difficult. It took about 1-2 hours of actual work (including applying high temp paint to cover up the cut area). It fits perfectly now.
