Query: This card reader stinks

Don't bother purchasing this device. Every time I put in my cards, they would only read intermittently. I took about 30 min to download photos that should have taken about 2 min. I have had similar problems with other card readers although this one was the worst. The best solution, don't bother with card readers and just hook your camera up directly to your USB plug with a cable that fits your device. Always works fast and easy.
