I am sorry the website is not tuned up. It is getting bit long in the tooth. It was done by a friend while I was totally focused on building the mold for the shoulder pad so a few things I assumed that would be understood were left out. My webmaster now works for a TV production company and I have not found the right person to replace him.
The UPstrap camera straps are made on a single piece of 62" long web that is rated at 1100 pounds with no sewing. For those of you that haul ten grand on your shoulder. . .this may allow some peace of mind.
One would need to try the UPstrap to see if it grips better than other straps. Since the non-slip is on both side of the strap, we can assume that it is at least better when if flops over. . .as they do. I've used all of them and I know, but you need to find out for yourself.
As for swivels, it is one more part to break. While the vast majority of photographers don't haul $10,000 on their shoulder 10 hours a day 7 days a week. . .there are those that do. They are the guys and gals that count on their gear to work. They have found that less is more. Untwisting the strap is really no big deal, a few twists of the wrist and it is done, a small price to pay for added strength. . .IMHO
The larger problem is the quick release. Again, until I can finish one of the quick releases that I know will not eventually fail and cause the $10,000 crash, I will not release on. The good news is that we are close on that issue.
Roberts is a dealer. They ship international as long as your willing to do a wire transfer.
Keep in mind that we offer a 60 day money back guarentee. If slipping shoulder straps are and issue for you, then try the UPstrap. If you think that the non-skid on other brands is as good as the UPstrap then you are assuming something that you have no direct knowldege of. The guys that endorse my strap are known worldwide and carry a camera A LOT and the UPstrap is what they choose. If after trying the UPstrap you want to go back to what you had before, send it back and I will refund your money, but not your shipping.
I realize that some will prefer a different strap. I have no problem with this. I do think it is impossible to make this judgement unless you actually try it. If you insist on swivels then this is not the strap for you.
Keep in mind that the LT strap is NOT for a camera but for a bag. While one web is 1" and the other 3/8" (industry standard for camera attachments) both have a break strength of over 1000 pounds.
Again, when you give the UPstrap a try you might find that a simple 3/8" web works better than others. But again, you will not know, unless you try.
I hope this helps and again I am sorry the website is not a bit better.
