I purchased these a little while ago. They work ok on touch screens, but not great. And they are already falling apart. You get what you pay for.
Bought 4 pairs meaning to buy just 2 pairs. Make sure you read the description that the sale is based on how many Pairs.
As far as working I tried 2 pairs and it required my to pull the fingers tight and press hard for them to work.
They do work as gloves in general.
