4 out of 5 eggsCool Multi-card reader

Pros: TINY, reads multiple cards at once, can copy from one to another

Cons: so light that it falls over, gets pwnd by its cable, annoying red glow of internal LED when connected..

Other Thoughts: No complaints. Needs to come with a velcro pad to stick it to your desk, or even the front of the pc, once and for all.

1 out of 5 eggsOnly comes with 2 Micro SD Adapters

Pros: Compact

Cons: Only comes with 2 Micro SD adapters. I was specifically buying it to do 4 micros SD cards at the same time. Now I have to either limp along with 2 slots, or buy 2 more adapters. Other reviews suggest I will also have to remove the adapter and plug it back in each time for the reader to recognize the new card. I think this could have been thought through a little better.

5 out of 5 eggsGreat niche product

Pros: Doesn't get bogged down doing transfers from multiple cards at once. The build quality is actually better than the images suggest. Writes at 10mb/s (max I've been able to get from my cards) without a hiccup. You'll probably max out the USB 2.0 bus before you max out the reader. Wish a USB 3.0 model existed.

Cons: The cord it came with is super short. Doesn't detect when microSD cards are inserted into the adapter -- you have to insert the adapter with the card already inside or it won't see it.

Other Thoughts: Does just about everything you could want a desktop SD card reader to do.

It's definitely a niche product but if you need this many slots it's a godsend.
