Pros: I bought 3 of these cards for my Nikon D80 camera, they were the only class 6 rated card available at a reasonable price. (Each class on SDHC corresponds to the MB/sec, so a class 6 is 3 times as fast as a class 2, which is what most cards are) The cards work perfectly, and are very fast. My camera can write 60mb (6 raw files) to the card in about 8 seconds.

Cons: Since these cards are SDHC instead of SD, you must make sure that your camera, reader, etc is compatible with SDCH. I had to get a new SDHC reader (Sandisk Micromate) but it is compact, and reads a 4 GB card in about 3.5 minutes.

Overall Review: Don't be confused about 100 speed, 133 speed, etc SD card ratings. These are speeds which might be achieved under ideal conditions. The Transcend class 6 cards tested out as well as a Lexar 133 speed card, according to an online report. I can store about 390 raw files (10mb each) per card.

Pros: Fast- when it works. Good web interface.

Cons: Poor reliability. Repair facility didn't repair it. Don't connect an external hard drive to your router, or the world can see it. Look up this severe security flaw on the web.

Overall Review: When I initially got the router is was in firmware recovery mode- a bad sign. But the tech guy walked me through the process, and it worked for a couple of weeks. Same problem happened again, so off it went on an RMA. Came back, and the problem wasn't fixed. But the problem is intermittent, so I didn't know it was still bad until after the short warranty. After seeing my previous review, ASUS got in touch. Lots of messages back an forth, but the end result is that they'd be happy to charge me to repair it. As I see it, they still "owe" me for the correct repair the first time, and I don't trust them to do it right anyway. So trust the low review scores- too many bad "refurbished" routers, and if you have a problem, good luck getting it fixed.

Pros: High speed, good user interface

Cons: unreliable, goes into firmware recovery mode on it's own

Overall Review: When I got this unit, it did not work out of the box. Asus support finally figured out that it was in recovery mode, waiting to have the firmware uploaded. This should be a very unusual situation- it's hard to even find info about it on their website. Downloaded the software, ran the recovery process, and it worked well for a few months. But every few months the router locks up, and when power is cycled it often goes back into recovery mode. So I need to unplug everything, connect it to my computer, change IP settings, and run the firmware recovery. Sent it back to ASUS for repair/replacement- got the same unit back, no change. So now I'm stuck having to go through the recovery process a few times a year. My old L- brand router wasn't fast, but it just worked....
