UltraFlex Rifle Slings - Has anyone used one?

[andersonjk4]

I am considering using an UltraFlex rifle sling on my new .300 Win Mag, but I have never seen one in person or talked to anyone who has.  They look like a good quality, made in the USA, gun sling, but I would like to hear some first hand opinions, not from outdoor writers who may or may not be a little biased, about them before I drop $40 on one.  Here is a link to their website if anyone is interested in checking them out.
