Puck technologies, perfecturine, clean pee, urea sample....they are all a huge rip off. The products work like crazy but you over pay like mad. You can get the same kits to transport it off ebay for half as much and get your friend, mom, grandmother, little brother, even your dog to pee for you. Most of the places that sell human urine don't even test it before they ship it out to you. The mark up covers any refunds in case someone is smart enough to offer a charge back through the credit card company if it fails. The synthetic works well but is way over priced if you can get it from someone else. You can get most the supplies from local medical shops but it is cheaper and the product is more inclusive if it is bought wholesale. If anyone is interested in selling on ebay the community could use the suppliers and you can find wholesalers pretty easily. I cant sell because of my job, but if I lost my job; I would sell this stuff in a heart beat. At whole sale, kits cost about $6-8 and sell on ebay for &15-20. Good mark-up!!
