Query: Very Solid and very quiet

Just got this a few days ago and have been very impressed with its stability and ease of setup. I've used other trainers before, and this one is amazingly quiet and stable. I also love the quick release feature, so swapping out bikes takes literally 30 seconds (important because my son and I both use it).It's very quiet and does NOT get hot. Used it for 2 hours and it was just warm to the touch, but certainly not hot.
