Nickel Alert - No Nickel - 2 Pack of Nickel Testing Solution for Jewelry, Watches, & Belts, Perform 400+ Tests on Any Metal Objects

I purchased this product a while ago and have been testing a ton of stuff with it. I saw one of the reviews that recommended using vinegar prior to testing to ensure you could get an accurate result. I tried both ways and found that the vinegar did get me a result faster but the result was the same either way for every item I tested. It is difficult to get 3 drops exactly, so I am glad I ordered 2 bottles rather than 3 so I won’t run out any time soon.I wore sealed eyewear, gloves, & a respirator when using this product since it really hurt my eyes when I first came into contact with the package. I recommend wearing the eyewear and respirator when using this liquid if you have the ppe available. A well ventilated area, gloves, and something to catch drips are non-negotiable.When I ordered 2 bottles, my first package had leaked in transit through the first ziplock bag. Luckily it is double bagged so it did not get into the mailer. It was still unexpectedly painful to open the bag though, hence my earlier ppe recommendation. The seller was very responsive when I reached out and quickly sent 1 replacement bottle.I would 100% recommend this product to anyone who is concerned about nickel content.

I have had nickel issues for years and only recently went to an allergist who confirmed I have a severe case. They recommended I buy this product to see where my issues with my eyes are coming from. I just used this product and was amazed. Some of my household items it instantly turned bright pink, others I rubbed for 15-20 seconds and it either showed nothing or a slight pink. It’s so interesting to see what is full on nickel and what only has trace amounts. Will be purchasing the nail polish item to cover some things. Thank you! Oh, easy to use.

Full disclosure: I'm a little salty about this because my order was improperly packaged, causing one of the two bottles to leak into the outer container (a sealed bag). The fumes when I tried to open the package were awful. (Strong smell, yes, but also enough to make my eyes burn.) I assume this was a rare packing mishap and will temper the remainder of my review on that assumption, but if others are having similar experiences PLEASE POST THEM so people can see if this is in fact a recurring defect.The testing solution works as intended. I tested it on... wait for it... a nickel (which is actually 25% nickel in copper), and the test result was a very clear positive. So now I have a way to tell if an article contains nickel, which is fundamentally what I was after.However, even without the major mishap in the packing of my particular order, the bottles they use are not a good choice in my opinion. I assume they've been chosen to save a few cents. What they are is plastic bottles with a reducer-type dropper insert. I find it very hard to dispense liquid from these accurately. I end up using too much in service of making sure I use enough, which is a problem because of waste and also because - again - the fumes are NASTY. Not above suggesting wearing some sort of mask to use this stuff.

I love the concept of this product but pretty frustrated so far. The instructions say to rub on metal and if the cotton swab turns any shade of pink, nickel is present. I rubbed on several items which I knew to contain nickel and the swab turned gray, not pink at all. This was really confusing because I wasn’t sure if the swab was picking up dust or dirt or if the item actually contained Nikel. Be aware that if you use this product on yellow gold jewelry which has been converted to white gold by dipping in rhodium, the color will be removed and you will have a yellow gold spot on your jewelry. If you were testing on a gold ring, make sure to rub on the inside, not the outside. I definitely feel this is overpriced for what you get.

Having developed a severe allergy to nickel, this is a tremendous help! Very quick, and very definitive. I've found nickel in unexpected places - and found NO nickel in places I DID expect it. Knowing for sure whether I really need to replace something or not is very helpful! I first got the set with one Alert and one Guard, but quickly went through the Alert bottle (and a gazillion Q-tips!) so ordered this set. I have (well, HAD) a LOT of jewelry, and was testing virtually every metal object I touch in my house, and there are an astonishing amount of them that you don't think about until you have to: zippers, buttons, appliances,utensil handles, knives, pens, cell phones (not in cases), magnetic clasps on wallets, purse pulls, keys, glasses frames, dog collars, pots and pans, letter openers... It's crazy!
