As far as I can tell, they seem fine. They're thicker than the originals that I'm replacing. I bought all standard size seals. I actually emailed the seller my measurements and he told me what size to order. He also didn't have a full set of neck, wrist, and ankle, so he just added the ankle seals when he sent me the invoice.
The neck seal appears to be the "normal" design. The wrist seals are the "bottle" style, which is what I'm used to. Although they seem to be a bit shorter than the originals, but it doesn't look like it will create any problems. The ankle seals are the cone type, but seem great.
I hope to install them this weekend. I'll take some pics and post them up when I can.
