Qmaster reliability vs BBQ Guru

Hi,

Can anyone attest to the reliability / durability of the Qmaster for the WSM 18.5"
I am weary since its from China, but hey, lots of stuff is from China.

Which is the "go to" model to link to the WSM from QMaster?
Does anyone have the Qmaster and a competitor, say from BBQ Guru to contrast/compare the too?

Thanks for any tips

I don't have a comparison, but I purchased a DigiQ a few months ago and am TOTALLY satisfied with it on my WSM 22.5.
