Question on FEISOL QR Plates

[kal444]

Does anyone have experience with FEISOL QR plates?

QP-144750 and QP-1447100

Are they arca style compatible? They certainly look like they are, but it's not very clear on their site.

Since they are pretty cheap, I might pick up a couple for use with my non-workhorse cameras.

To answer my own question. Here is the reply from FEISOL USA:

It should be compatible with arca clamps - of course we cannot guarantee
compatibility with accessories of other makes.
