The Wrist Roller Model 401481 product design and ESPECIALLY THE MANUAL (online) is flawed, as regards the strap's use and reliance on Velcro to secure the end of the strap to the safety clip (which easily attaches to the pull road that holds the weight plates). The Manual clearly states the Wrist Roller is "shipped FULLY ASSEMBLED" -- but that is not true. One must go online to view the Manual for instruction on how to attach the safety clip to the strap, BUT THE MANUAL IS DEVOID OF ANY INSTRUCTION ON ATTACHING THE TWO ITEMS TOGETHER. It is left to one's imagination, or else calling Titan. I called Titan, and it took about 20 minutes or longer on the phone to get any helpful information, explaining "there is a loop" near the end of the strap where the Velcro-coated end is supposed to "slide through" (after looping through the safety clip). It is extremely difficult to try to get the Velcro end of the strap through that narrow loop, because the Velcro surface keeps grabbing onto the inside of the loop and doesn't "slide through". MY RECOMMENDATION: Either ship the Wrist Roller FULLY ASSEMBLED to the customer, as claimed in the online product Manual, or else update the Manual to give DETAILED INSTRUCTIONS on how to assemble the product once it's been received. - Charles Garcia
