I bought this vertical rotisserie so I could make authentic Al Pastor tacos for a big party we planned. It's not dirt cheap, by any means, but the price is reasonable if you entertain and enjoy cooking. For my purposes, it was worth taking a chance on it.I did a test run with a relatively small amount of Greek chicken, cooked shawarma style, and that turned out great. When it came time to make the Al Pastor for the party and stack up the meat to build up the trompo, it all went very well. I piled on the marinated meat along with pineapples and onions and wrapped it up to sit and firm up in the fridge. I put it on to start cooking about an hour and a half before I expected guests to arrive and it was perfect timing. I adjusted the heat up and down as needed and we cooked and sliced off meat for about 2 more hours. The propane burners provide plenty of heat and are very adjustable. The resulting tacos were great! Perfect street-food style just as you'd expect in Mexico City. :)I'd say that the 13 lb capacity might be a little ambitious. I probably got 10 lbs of sliced pork on the spit but I also had some pineapple, etc. It's probably capable of 13 lbs but it would take some careful stacking and trimming.I'd seen from other reviews that the grease pan is too shallow and will definitely leak if it gets very full at all. I fixed that by installing a short length of 1/2" silicone tubing in the hole in the grease pan. It's a tight fit in the pan and a tight fit over the shaft that turns the spit. Not a drop of grease went anywhere but the pan.We'll have to see how well it holds up to repeated use but all in all, I'm very pleased with it and I expect to make good use of this machine. I've promised my German friends that next time we'll do Doner Kebab. :)
