Review (3/5): Package had been opened so I refused to test this item
First off I will state I got this at a discount in exchange for a honest review and evaluation. Second, when I opened the Amazon box both this item and another I had ordered had been opened. The Nupro Joint and Immunity Support for Dogs had had the paper cover partially removed and the powder spilt into the Amazon shipping box. Similarly, the plastic cover over the threading tool, the tweezers and the small razor had been partially ripped open about 3/4 th of the way open. I therefore refused to use it so I can not say if it works well or not. If it had just been one item I would have just thought that the glue that sealed the plastic cover to the paper backing had given way. But with both items having been opened I suspected tampering. For the price I just didn't want to go through the hassle of replacing this item. My cost had only been $0.97. I can say however that a quality tool, such as the Stainless Steel R.E.M. Spring which is just under $20, works extremely well. I was hoping to find a cheaper version that worked in a similar manner. I gave it away to a friend with coarse facial hair.
