I would say it's a decent product, I got it, and the delivery wasn't bad in time, ordered feb 3rd, arrived feb 20th
It came from UPS after it arrived in canada, looked like a new labeling too.
I ordered the r4-sdhc, they sent me the newest version for the 3ds and older models, that supported my ds lite, which was nice.
The weirdest part was their site's SSL cert expired right after I bought it, so I too thought it was a scam.
Be aware any support service requests should be sent to alltechgear.com, which apparently owns this site, that's how I ended up getting better service.
