Answers:    They are all right.. I approaching the cheapie one's from Walmart $4 for a pack of 12 and they are great for wiping up spills.. Cleaning up the children after a messy lunch.. They work nice on window and on furniture as well. Just don't use textile softner on them..
How can i gain..?
You got ripped bad.They absorb plentifully of fluid but thats about it. They streak, and they don't rinse out capably as advertised. You might want to consider something else to make a contribution for Christmas presents....Sorry
