"Examples of things I've been able to boil with these miracle chips: Dirigibles, pay phones, a 1982 Pontiac fiero, the neighbor's shingles, a javelin, a cowboy hat, a shovel, a shoe just like in gold Rush! Go figure, of all the things I've purchased from Amazon: boiling chips (a far superior broken glasswareor porcelain ware)- to allow nucleation via cavitations of a highly irregular surface area, diaper balm- for the bum of our son, and Pb bearing solder- for the ladies: are the only 5 star winners. 70% of all scientific equipment and tools along with 98% of Amazon's customer service are unfit for living organism consumption. Disclaimer 2: If you're my neighbor: look buddy, for the last time: I DON'T KNOW WHO BOILED THE SHINGLES OFF YOUR ROOF OR YOUR COWBOY HAT."

The elastic pen loop is a great add-on and makes storing my .7mm needle tip ballpoint pen a cinch - super convenient. It's a steal at twice the price of a moleskin and yet it's cheaper!"
"I purchased this item knowing that in a few months, I will need to replace my current bullet journal. I am currently using the Essentials Dot Matrix Notebook, A5 size (Bullet Journal). When examining the ribbon, glue is only placed at the tip of it, and glued on the top of the spine of the notebook. In my current journal, the ribbon glued more than 1/4 down the length of the spine of the notebook, which makes it more secure. As far as smudging, drying or bleeding, I haven't yet tested that out, so I will update this review when I start using it daily. It caught my eye because it looks well built, sturdy, and it resembled my laptop case that I purchased for my MacBook Tomtoc Ultra Slim 13 Inch New MacBook Pro Retina 2017 & 2016 | 12.9 Inch iPad Pro 2017 Sleeve Case [Felt & PU Leather] Laptop Protective Bag with Accessory Pocket - Classic. - The pen strap is GENIUS!!"
"The pen loop is genius and lets me keep my pen with me without destroying my journal. The pages (I got dots) are surprisingly high-quality, and none of my pens (microns and some prismacolor pens) bleed through at all, even when I push really really hard or go over something a few times."
"The feel of the pen on this paper is simply incredible for the price of the notebook. So much so that even notes that I would normally use the laptop for I find myself reaching for the LEMONE as the writing experience is simply addictive."
"The packaging it comes in is something I was not expecting and is very nice; it's a black matte encasing with the Lemome logo on one side."

Find Best Price at Amazon"I just attributed it to the fact that I have been working many long hours, not getting enough sleep and slacking on my healthy diet. So when I had the opportunity to try out these HealthyWiser pH Test Strips complimentary in exchange for my honest review, I was intrigued. I have used pH strips to test out the water in our fish tank, but never heard of them to use as a health aid. When your pH levels aren’t properly balanced, you can experience physical symptoms such as indigestion, fatigue, body pain, and headaches. If you try out these test strips on a day you aren't feeling so great, chances are your pH level is probably on the acidic side. Reduce or eliminate acidic beverages such as soda, alcohol, coffee, processed fruit drinks, and energy drinks.etc. Eat lots of low acid fruits and increase your intake of green, leafy vegetables. Personally, I think this product is great for anyone into natural medicine and those who need to keep to a strict diet such as diabetics or people who suffer from any type of digestive illness. After testing your pH daily, you will probably realize that it is time to get your diet and eating habits back on track."
"Do to a health issue we needed to be able to check a family members ph level."
"Disclaimer: Before making a purchase, I research a product thoroughly, and I depend on honest reviews to aid in my decision making. This product was received for free or at a discount in exchange for an honest and unbiased review. While I have shaken my head at some of the 5-star reviews I have seen other professional reviewers give to lousy 1-star products, simply because they received them for free, I do my best to keep my reviews thorough and unbiased."
"Your mouth tends to be a bit more acidity; however, it gave the exact readings as the urine. I could definitely see a difference when I had consumed more broccoli, or lemon water on a particular day than not. I also tested with other family members and their readings were accurate as well and the colors matched as well."
"Use UTI test strips to test for infection and if nothing shown positive then use this to get urine Ph in the proper level per this product instructions."
"I decided to get those test strips to test the acidity level of food and drinks I consume every day ."
