Spun off from
How can you support local music shops anymore?There are a couple of local guitar shops that I visit from time to time.
Recently I was in the neighbourhood of one of those shops and remembered that I was thinking about one of these.. (Goofy I know)

As for the strap. To what purpose?
Everything that JOYCEfromNS said below.
Balance an aleviate the weight I suppose for those bordering overuse/stress injuries AND no strap pins needed. Soo ST You Like

I had made something out of two of these
Levys Clasical Guitar Strap

I was trying to avoid the "moment's inattention leading to a lifetime of regret" issue with a single hook approach. Basically -you have to keep a hand on the guitar or an elbow on the lower bout or else the guitar is going to flip forward onto the floor. In my home-made approach I added another hook from the top. And then I found that Neotech already had one.
Do I like it?
It's okay - comfort wise. The balance is alright. It feels weightless. The guitar feels weightless too. It can still tip if the guitar is neck heavy, but it won't end up on the floor.
But the big win, is that I can use the upper strap as a point to clip on a mini-condenser microphone on a thing goose neck. I'm experimenting with that, but it seems to work pretty well.
Well, just gotta say ... silliest thing I've seen in a while.

It pretty much disappears if you wear a black shirt and use it with a black guitar.
Looks like a bustenhalter...or, as Benny Hill used to call it...a "keepemfromfloppinstoppin."

I have a whole new appreciation for the discomfort of those so encumbered.
