I have had some really good success with my MES40 since I purchased it. But those smokes were 1 of those, maybe 1 of these, or maybe a couple of those other things. This is my first smoke with a relatively full smoker. I have 5 boneless butts in there (from Costco) and there appears to be room for one more (halved.. or... not tied). Yeah... this is WAAAAY out of my league. But since its for my daughters wedding reception next weekend, I gotta make it good. This just went in about 5-10 minutes ago. I have a Maverick but I also bought the Weber Wireless Thermometer today. Initial testing shows that the Weber is more accurate than the Maverick. The Weber showed boiling water at 208 on both sensors. That is right on the money for my elevation(2000ft above sea level). The Mav showed 200 and 204 on the sensors. At room temperature, both probes showed 78 on the Weber which I believe is spot-on. I dont recall what the Mav showed but the probes were about 5 degrees off between the two. I will be using both the Mav and the Weber.
