I haven't used my new MES Bluetooth yet, but did get it seasoned today. Here is what I observed vs my Generation 2 Smoker while seasoning it.
1. It took 28 minutes to heat up to 275 degrees vs 45 minutes to get to 265 - 270 on my Generation 2 Smoker. Even when new, my Generation 2 Smoker never reached 275 in 28 minutes. More like 40 minutes when new.
2. The heat coil shut off at 275 degrees as it is supposed to do. Temp continued to climb to 283 degrees the first time before dropping back down to 273 degrees. After that it would heat to 275, shut off and stay at 275 for a bit, drop to 273, come back on, shut off at 275 and stay at 275 for a bit and drop to 273 and come back on, etc. etc. and cycled perfectly that way just like clock work for the whole time.
I don't know if when once I start smoking meats, if it will work that perfect or not, but it was perfect while seasoning it today. My Generation 2 never did even think about running that good, not even close.
3. My Generation 2 when new would go up 10 degrees or a bit more over the set temp, then drop 10 - 15 degrees below the set temp, come back on and repeat and etc. etc. etc. After approx 18 months, it would drop as much as 25-30 degrees, then go back up but never reach the set temp again, yet the oven thermometer I had on a shelf in it would say the temp went back up, sometimes as much as 25-35 degrees over set temp. For example, I could smoke at a set temp of 215 and it would drop to 180-185, then go back to 195-200 and never go any higher, yet the actual temp did go higher like up to 235 and on ocassion even 250, while controler would read 195-200.
A controller change and heat coil change never cured the problem. Masterbuilt then said that I needed a new box. Thus I now own a new Bluetooth ...
