Both have their points but both have their limitations as well. I bought a new Guru CyberQ-II and used it two times and sold it to another Q cooker. There was nothing wrong with it; it just would not do without great effort what I wanted.
The CyberQ technically “can” be run wirelessly but they recommend on their site having two computers and a router to do that task, (Read the Online Manual). It for me seemed to be more stuff than I wanted to hook-up to do that task, and seems to me to be way more than I wanted to drag to a comp. That’s why I sold it and went with the Stoker, it had nothing to do with the quality of the Guru unit, it did its job running the pit great. The Guru’s are in my opinion a much more “User” friendly devices; you can be much less computer savvy and use the Guru’s just fine.
The Stoker will do what I wanted that’s why I bought it, it will run a Pit-Stoker-Computer setup with much less equipment than the CyberQ requires, but it was built for those with much more computer time under their belts and is a much less of a plug & play unit that the Guru’s are. I haven’t cooked with it yet so I can’t talk about its pit management skills. If you understand terms like I.P. Address and Subnet you will more than likely be just fine, but if you’re like me and need a little help in that area, you need to read and learn these things first or you’ll have problems.
They both will run a pit, they both will give you temperature control that is almost impossible to do manually. But they do it in different ways. I have been thought the buy it an sale it later route and like most things I lost money in the process. If you are looking at these units take time to read all the info you can before you buy to determine which unit will closest match what you want, go to the websites and download their Owners Manuals and read them first. Just my 2 cents, it’s free so take it for what it’s worth.
