I stumbled across this a while back when Mistress and I tried out a DreamLoversLab 2k / CB6000 cage for awhile. The product seemed to have a lot of potential and features but we found it sadly not very durable. There is an additional section of articles though on "Male Training Theory" http://www.dreamloverlabs.com/theory.php that looks (to me anyway) to be written from Mistress/Female lead (led) side. Some were interesting. I also tried out the training/testing features off the CD that we download. Very specific about how to perform chores and activities. Of course in the end its about what pleases Mistress (and my KH) so everything at that site is relative
I think these two articles are really good to set a right mindset. These are not training article though The one for subs : https://at.tumblr.com/sanaslave/706410914853863424/qace2hezebtd The one for Owners: https://at.tumblr.com/sanaslave/694184940996362240/498p5xtl02im Other articles are also great though.
