I already left a good feedback rating for the prompt shipping and great packaging of the product, but I have finally had time to put Screen Joy to use and here are my impressions.Like most people, I have plenty of touch screen devices around the house and with also having a teenage son and a 8 year old daughter, every device I own has smudges and fingerprints all over it.So shopping for a computer screen cleaner on Amazon took some time to research. I ultimately gave Screen Joy a try because the product is new and the product maker advertised that the screen cleaning formula is made for modern devices.The packaging and labels of the product on the Amazon page looked really professionally made so I felt as if they put some time into developing this.I also looked at some of the other products made by the company that makes this (IX Better Home) and they have GREAT reviews for their other stuff and people really seem to like the customer care they provide. That's really important to me and the shipping was free so I thought, "Why not?".Ok, so my first use was actually on the dirtiest item in the house... my Microsoft Surface tablet, who knows what my daughter actually has on her hands but spots of gunk had actually DRIED onto the screen. Gross.Screen Joy just cleaned that gunk right off with no problem! My Surface tablet looks like it's brand new now.Good start out of the gate, which made me eager to try it on other things in the house, my flat screen TV and three smartphones are all super shiny and glossy now! Although it didn't say to do this on the packaging but I cleaned my keyboard with it too haha. Worked great !Really excellent product.Additionally, I was really quite impressed with the quality of the cloth that came in the package. It's a great size in my hand and I could feel it was high quality right away when I handled it.I am a project manager at Microsoft headquarters and will be updating this review when I take this screen cleaner to the office. I am curious to see how my colleagues like using it.5 stars from me Screen joy.. nice product
