These type of manufacturers pop up everywhere. In additional to cost, performance and reliability, the important question is will they be here tomorrow? If they are readily available to you, give them a try. I am all for supporting the underdog as long as I won't be left without recourse if things do not work out.
I looked at their warranty policy. It states coverage during the "warranty period", but it doesn't state what that period is? Amazon states 3 yr.
Write speed is slightly less than AngelBird, ProGrade and SanDisk. Varied based on where I looked. But this won't matter for a stills shooter.
Looks like 20 yrs in business. 4 subsidiaries, an HQ and 1 factory world wide.
There US office is about 30 min from San Francisco.
Its certainly got a low price.
