I just wanted to say I am impressed with the LavaLock product. Yesterday was my first grill with it installed. First off when you first start your Treager and it's set on smoke mode to get started, there was a night a day difference with smoke leak. Normally it would be coming out the side of the lid, this time only out my stack and grease port. It came bellowing out thick. But there was another nice surprise and that was a more balanced temperature. I verified this by my Meater + after cooking. It charts and graphs your temps and fluctuations. With the LavaLock my temps were steadier, which in theory means less fuel burn as well. A great product for the price.
