These USB adapters are very affordable. I bought 3 and had to send 1 back immediately. The metal connection that plugs into the computer's USB port was loose and therefore unusable. I should have just returned all three in the first 30 days. In the next 3-6 months the other two also expired. However, it was too late to get a refund for them. What a waste of money.
