Duda Energy Bottles of 99.9+% Pure Isopropyl Alcohol Industrial Grade IPA Concentrated Rubbing Alcohol 4 Gallons Total, Clear 32.12 Fl Oz (Pack of 16)

I never used 99% alcohol before and I cant test if it is really 99%, but honestly I don't see any difference in performance (cleaning build plate for 3D printer) between lower grade products. I expected it to evaporate faster at least. So I may be wrong and have high expectations, but that is what I am experiencing. In my case none of the bottles were open and they all were full unlike some reviews stating.

Works well and is a good product

Rubbing alcohol has been difficult to find, when I have, it's the 70% variety, 90% is usually the highest I've found. While this product is more expensive than say a big box store, I expect 99% alcohol to be more expensive. I use alcohol for a couple things. 1. Clean my water bong. 2. First aid. 3. Alcohol stove I made for camping and 4. For various household things. This product works awesome for all of the above. The first time I cleaned my pipe, it wiped out all the muck instantly, no scrubbing. My alcohol stoves burn cleaner and hotter, boiling water in about 3 minutes. Fantastic!!! Now as far as the company I would give 10 stars. The product arrived in less time that was stated and one of the bottles had leaked. This to me is a carrier issue not the sellers, it was packaged very very well within the box it came. The bottles were wrapped in a plastic bag so if there was a leak it would be contained, which it was. Also, inside the box was stuffed with a thick paper to prevent the bottles moving around inside again I believe it did its job. Having worked for various carriers before, I can attest they don't really take great care in handling boxes and I could see a little denting on one corner. This probably caused the one bottle to leak. I emailed the seller and within an hour (awesome) they responded. I actually emailed just to inform them of the leaky bottle, to my surprise, they sent a whole replacement bottle immediately and I received it a couple days later, an offer they made. This to me is incredible. They stand by their product and they act with integrity valuing the customer, this time it was me. A++++ I will buy products from them in the future without question!!

Great value for the money and well packaged, smell isn’t overpowering either. It certainly does do as it says .

It did have a foil cover on the bottle when it arrived. Unfortunately, the bottle doesn't have foam under the cap to help seal the bottle once opened. I'm hoping it doesn't evaporate too quickly. If I gently squeeze the closed bottle, air escapes. They also claim the cap is screwed on tightly. Mine was not and was loose. So had that foil not been there, neither would have been my alcohol. It does seem a good strength product and did what I expected it to do. I used mine to make dragon's blood ink. For what this costs, I think they could make a better cap and seal system. I guess this makes you come back for more.

The item arrived from seller faster than Amazon Prime (4 days), and is fully as described. Note that there appears to be an inch and a half empty at the top, but the actual contents ARE the full 1900+ ml including TWO bottles, both with seals and well packaged. The additional space is common with 99% due to room for condensates in heat.Some reviews have knocked both the empty space and the price as gouging, but if you make your own sanitizer by diluting this and adding gel, you'll get a gallon plus of sanitizer for $45 which is going for over $70 anywhere else, on the rare occasion when you can even get them (this review is in the middle of the Covid scarcity). Pricing is logarithmic, not linear, as you go from 60 to 99% purity, industry wide. Sanitizer sprays are even more and you can dilute this by almost half (dilution also is nonlinear) for spraying door handles, hands, containers, etc.Responsive seller, great product, recommended at anything under $20 per bottle for this quantity and purity. We tested both purity and quantity and both are as described, which is NOT true of others we have purchased that ended up coming in unsealed bottles! These bottles were both individually machine sealed UNDER the caps.

I use rubbing alcohol everyday and although it's never expensive it does add up. Finding the big concentrated bottles has really been a saver.

I SURVIVED A CHEMICAL EXPLOSION, BURNT 3RD DEGREE OVER 48% BODY. AFTER 23 RECONSTRUCTION SURGERY I HAVED LEARNED A BIT ABOUT INFECTION RISK. NOW, AFTER A CANCER DIAGNOSIS OF TYPE MFA, ONLY SEEN IN BURN PATIENTS, STERILE PRACTICE IS PARAMOUNT HAVING SURGICAL SCARS. LAST YEAR DIAGNOSED GYNOCAMASTIA BILATERAL CAUSED BY "LOW T" LEAVES ME HANDLING STEROID APPLICATION. BOTH BEFORE AND AFTER. EVERY MORNING I MUST IN CONSIDERATION OF OTHERS AND PETS, CLEAN ENTIRE AREA STARTING WITH MY HANDS, USING ALCOHOL EVERY DAY!THIS PRODUCT IS OUTSTANDING AND SHOULD BE USED WITH CARE AND FOLLOWING INSTRUCTIONS AS WELL AS ⚠ CAUTION AS OTC IS 71%-91%, A BIG DIFFERENCE. I CAN NOW REST EASY USING IT SPARINGLY BY A MINI-SPRAYER TO THEN CLEAN VANITY. ADDITIONALLY, I HAVE FOUND NUMEROUS USES AROUND THE HOUSE IN CLEANING UP TOOLS, BROKEN OBJECTS (PREP) BEFORE GLUE/BOND, ECT. TODAY I USED IT TO STERILIZE MY KEYBOARD, SCREEN AND JUST ABOUT EVERYWHERE WHEN DILUTED. NOTE I SAID "DILUTED" AS IT WILL EASILY MELT THRU THIN PLASTICS AT FULL STRENGTH. MY TBI HAS NOW TAKEN OVER SO I WILL END BY STATING 5-STAR!!!!!
