I use it daily 5-10 minutes at a time. I won't go to the range without swinging the weighted rollers (long for woods, short for irons). The product only recommends partial swings, but I have no problems working through total motion. Although my laser devices are as useful for working on plane alignments, I like the guided roller for the first move off the ball (my tendency is a fraction outside on takeaway. The heavy weight of the weighted roller forces full release even for those (most unfortunate)of us with the strongest "hold off" tendencies through impact. There is no clubface on the roller, but there is a rod between the handle and roller to place a clip or other "makeshift" clubface in order to monitor hinge actions. It is very interesting to monitor the natural hinge actions which result from imparting mostly right hand vs. mostly left handed forces through the impact interval (no surprises, but very cool to confirm TGM concepts). Although I use the Explanar in front of a large mirror, muscle memory is best attained by not watching the roller make its way around the hoop, but rather focusing on a real golf ball placed on the ground and addressed as if one were intending to actually make contact.
