Pros: HUGE data capacity - 32 gig means I can shoot RAW format all day at the track without dumping to a laptop or changing cards Great price for the storage!

Cons: Each 32gig dump on my laptop brings me that much closer to filling the hdd. :) (Not really a problem!)

Overall Review: I've been using the Transcend disks for a few years now, and have never had an issue. Bonus for Canon 40D users - our cameras are not capable of the faster bus speeds, so 133 transfer rate is as fast as you need to go. Don't waste your money on high speed cards!

Pros: Simple setup - device was out of the box and working within 5 minutes on an IPhone. Simple instructions for IOS users.

Cons: Windows 7 users - you have to install the latest Prolific USB-Serial drivers to use this device. Windows will not get them automatically, and if it does, they are more than likely outdated. Outdated drivers will result in intermittant communication errors. It'll work, but not very well. On to the firmware update - I bought this to work with Harry's Lap Timer, so I needed to reflash to get the 5Hz update rate (look on Dual's FAQ page - it's the only link I found to the firmware update). Windows 7 users - DO NOT DO THIS UPDATE UNLESS YOU HAVE THE LATEST PROLIFIC SERIAL DRIVER!!!. The driver link in the update instructions went to a 404 page. Mine took a couple of tries to get the new firmware loaded... at one point I thought I turned it into a brick! Had to take it apart and disconnect the battery to recover. The MFC app they use to reflash will show a lot of errors and retrys - be patient! It'll eventually program.

Overall Review: Overall I'm very happy with the device. Not so happy with the tech support (still waiting for them to get back to me)
