I too have an Pitmaster IQ. I have nothing else to compare it to so my thoughts are obviously biased. It just works! I've used it on a cheap offset, that leaks like a sieve, and I've used it on my UDS. No complaints. The offset still needs tending regardless. The UDS has gone over night unattended many a time with excellent results. I've run it continuously on a deep cycle battery for 12 hour cooks with plenty of battery to spare. Just my $.02. Cheers!!!
