Bad Cards
I also have two of these cards. They have multiple read/right failures and are not recognized by computers (tested on 4 separate systems). The cards only seem to work in my camera and pictures can only be transferred through connecting the camera to a computer. I tried them in my Garmin nuvi 360 and one actually was recognized but when trying to transfer mp3s the same read/right/recognition problems occurred.
Do not buy these junk cards!

two 4GB SDHC cards, two intermittent read/write failures - stay away
UPDATE: PNY was very responsive in exchanging both SD cards under warranty. I contacted them by email (the only way), they asked for more information, then sent me a return authorization.

The entire process took a couple of weeks, but I'm happy to report that the new cards seem to work properly.

ORIGINAL REVIEW:
I purchased the (very competitively-priced) 2-pack of 4GB PNY Class-4 Optima cards for my Canon A570 IS digital camera and Garmin nuvi 360. BOTH cards have failed with intermittent read/write errors. Despite low-level format (FAT32) both cards continue to exhibit errors.

Interestingly, the 4GB SDHC Class 4 Kingston cards I own work perfectly in both devices.

Perhaps I got a bad batch, but given two failures, I would not recommend this card.

Leave it to PNY
to come up with something not too user friendly (see my review on my PNY RAM). But this is how the market is, you always have to upgrade.
Out of three card readers, none of them are able to read this card. I tried it on a friend's computer, & the same thing.
Using another external card reader, hooked up to my laptop, did provide a read, with out the camera!
I've tried finding drivers for my card readers, but to no avail.

Overall the card seems alright, albeit a bit slow. I use it on a back up, pocket camera, so it's not my primary card. I'll more than likely either buy someone else's card, or have one heck of a lag in dling pix from it.
Take your chances, if you find it for a great price.
