No smears, streaks, or any sort of weird residue like some other products I've used

Leaves weird streaks

I also used this on a display with a matte finish and there are no visible streaks, but I suspect that's only because of the lack of reflectiveness.

It doesn't leave streaks or harm my electronics in any way

I constantly get cloudy streaks on everything I clean with this product, including MacBooks, iPhones and TV screens

The cleaning liquid is apparently safe for even AR-coated screens (no ammonia or alcohol), but it leaves streaks worse than plain distilled water.

The cloudy streaks are very difficult to remove

There are no streaks and the microfiber cloths work great

My screen looks just as shiny as when I first unboxed my MBP

so perfectly I wanted to jump for joy - and I rarely have to do more than polish the screen with the grey cloth's soft side - it's as easy as and similar in motion and technique to wiping fog from a mirror or window

But again, the screen is no longer as clear as

Overall, I would recommend this product for its ease of use, as well as for the fact that you get a lot of product for your money.
