Where have these been all my life?
Color: Glitter Pink/Black, Color: Glitter Pink/Black
I don’t understand why anyone would give this set of little miracles a bad review. I have wasted way too UHC money on too many products that never get my phone completely street and smudge free, especially around the edges where the phone and the case meet. That’s the area I’ve wasted the most time trying to get clean, to no avail. I have spent way too much time wiping the edges and corners over and over, but they never are completely streak-free. I saw these and figured I’d try them; it’d not like I wouldn’t be able to return them if they ended up being a just as useless as everything else I’ve tried, and even if I did forget to send them back, I wasn’t losing a ton of money. The first thing I did when they arrived I pulled one of them out, shoved two fingers under the elastic band, a major selling point for me because it keeps it secure without feeling claustrophobic., and started swirling all around the edges of my phone. And within seconds my phone screen looked brand new. The oily grime stuck in the corners and all along the edges was gone within seconds. Without any cleaning solution too, which I love that it’s an eco-friendly solution to keeping all that grossness off of my phone and tablet screens. I was in the middle of making cupcakes and had the bright idea of smearing a bit of butter on the screen of my tablet to see what happens. The results speak for themselves. And there’s no gross oily residue left on the pad I used to clean my tablet either when I was finished. I’m sure there’s an easy way to clean them…I’ll look into that when the need arises. The only issue I have is that I can’t buy them in an extra large size for cleaning tvs. The small ones will work perfectly, but an extra large one would get rid of every streak, smudge, fingerprint and lint within a few seconds. And you get it clean without any cleaning spray. You don’t even need water. Just open it up and use. I’d buy one to keep behind every tv in my house in a large size! They are the perfect size to keep in your purse or your pocket. I bought the glittery ones; my ADHD brain is immediately drawn to anything that sparkles. And getting four for the price is beyond a great deal. I highly recommend these little wonders if you are like me and hate seeing your grandchildren’s fingerprints smeared all over your tablets screen when they hand it back to you. Or if you reach the same level of frustration I’ve reached whenever I’ve tried to get every bit of oily grossness off of my phones screen. These are going to make great white elephant and last minute Christmas gifts and stocking stuffers. They arrived a day earlier than I expected too. Get these. You won’t regret it. Until you try them and you regret that you can’t get an extra large one for your televisions too!

Hard to hold
Color: Shades of Blue
The straps is really tight, so it is hard to hold and maneuver. Colors are what I expected. The ability to clean screens is OK

Cleans without damaging
Color: Blossom
Great little item for laptops, tablets, phone ,etc. Cleans the screen without any damage. Love the strap which makes it easier to use. The cleaning side is soft and smooth while the strap side is harder and makes it sturdier when cleaning. Another great product from Fintie!

Great cleaning job!
Color: blooming hibiscus
This cleans your IPhone so it looks like glass. The finger prints do come back as easy. I have given these away and everyone likes them. Better than the cloth.
