Micro memory card with SD holder

It should work, but SD or SDHC cards are a lot cheaper for the big ones. The only other disadvantage is that if you drop a micro SD, you better have eagle eyes!

The only down side I've seen so far is that the older I get the harder it is to SEE the little thing. And my fingers seem to get way bigger when fumbling with it. Otherwise they work ok in my nuvi's.

It works well for me.

One reason for using micro cards (and an adapter, when needed) is that the one card can be used in more devices. My Topo maps on a micro SD card work directly in my eTrex GPS and work with an adapter in my nuvi.

If you shop strictly for price there is a chance - slim that the adapter will not work right. I've got a 4G micro that can't be read in the adapter that came with the card, but it works fine in one from a major manufacturer. Nothing wrong with the micro, just the adapter.

I have the opposite problem. Card works great in the adapter but can't get it to be recognized in a 1490 at all. I think this is a problem with the Nuvi and not the card however.

My 885 uses the micro, and I use an adapter for plugging into the computer. The low cost adapter doesn't work in my PC while the SanDisk does - with the cheap micro card.

Another compatibility issue is the some devices won't recognize cards bigger than the devices state card capacity. (You can't just format the card at a lower capacity.)

The only reason I was thinking of going with the micro card in the holder is that I might want to transfer the card to another device in the future. Going with the micro card and adapter gives me more flexibility.
