Over all, no problem of significance after replacing the original control (one of the probe slots was damaged). They never asked for the old control, so now I have a spare that works perfectly but only has one probe. The only other problem (a leak in the barrel end) was easily solved with high temp caulk for the rivet holes at the end caps. Have done briskets, butts, and grilled lots of chops, steaks etc. with great results. Discovered in temps below 40, that the max temp I can get with full throttle is about 470* which is understandable-no insulation. No problem for me as I can get good searing with my GrillGrates at that temp. However, much of their competition, now has double wall insulation. I would suggest that RT consider that option for those in colder climates, otherwise they might engineer some pad insulators. Otherwise a great product.
