Don't know what to put in a review for deionized water haha. It came on time and was well packed. I use this to clean my telescope mirror(s) yearly and it does the job well. Leaves no residue behind

This product is either a counterfeit or mislabeled. This is definitely not DI water, but is labeled as such. It contains high amounts of metals (tested by ICP-OES). Also tried it in a sterilizer, and I would have been better off using regular bottled water or even tap. So much white precipitate/scaling left behind. Don’t waste your money on this.

The water had a visible layer of brown sludge present under the seal. The conductivity tested at over 300 microsiemens per cm - Type 1 DI is supposed to be MUCH cleaner than this. I may have gotten a bad batch, but this is literally dirtier than the tapwater in my town, which has a conductivity of ~200 microsiemens per cm. You'd be better off with a $2 gallon of distilled water from a drugstore. Lot number was 20223521. Returning this!

The photo shows the residue from a 50 microliter droplet evaporated on a silicon wafer. It has more dissolved solids than tap water. This is either a bad batch (Lot number 05162257) or the product is mislabeled. The water even has a slight odor. Hard to believe.
