First up I admit to not being a fan of rigid shell saddles. I find them cumbersome as I don't always want to use a saddle when just out shooting for fun. I decided to try the S&J saddle out last year and acquired one through the U.S. distributor via eBay.
The quality looked good out of the package and the install was simple. Clean the surface of the receiver with alcohol, remove the paper backing from the self adhesive fuzzy half of the saddle and position it appropriately. Prior to install verify clearance of your forend in its most rearward position to avoid any interference with the saddle. I also punched a hole in the fuzzy panel before installing to allow removal of the receiver pin. Press the adhesive portion into place aggressively. I like to roll it out with a towel-wrapped dowel to make sure I have no air pockets and the entire surface achieves good contact.
Stick the saddle on its base panel and you're all set. The flex loops of the new saddle are very tight at first yet release the shells easily. They yield a bit with use but I still find it easier to re-load the saddle by ripping it off, stuff it full and slap it back on. After several months of use the loops have maintained excellent retention of the shells.
In the field the saddle works as it should. I load with my off hand over the top of the receiver and the S&J saddle has never come loose or interfered with my loading process. My dexterity is still the limiting factor in my personal efficacy

I have one niggle with the saddle but its easily addressed. The corners of the detachable saddle are very squarely pointed and somewhat sharp out of the package. I noticed some snagging in clothing and moving through heavy brush. I trimmed a mild radius on the corners with a razor knife and then melted them with a heated scraper blade. Definite improvement in the field.
All in all I'm very pleased with the S&J saddle and its minimal impact upon the shotgun when not being used. Nice and light with little physical intrusion. I'd but it again and I intend to add a few more to have on hand. This kind of saddle has some tactical advantages when used in conjunction with my SOE MicroRig.
Here's some pictures for your consideration:
