This utility is a must. The suggested effects work well and can be performed smoothly. I would suggest loading the loop on your wrist or hand close to when you are going to use it rather than carrying it on your wrist/hand all day. Also, once you start using a loop, it will eventually lose strength and elasticity so be careful not to use it past its "lifespan". Also, be careful when performing close-up against a white background. You are better off performing in dark or colored backgrounds/surroundings. The videos included will teach you the correct handling and technique. Lastly, as with any utility, remember you are the performer, not the utility. Practice your misdirection and your story to assure "invisibility".
