It works just great, Richard
I've switched out all my wider dulcimer straps with this 1" strap and just love the "less bulk". It's easier to store in its case too. I will never go back.
I like to refer to dulcimer straps as "seat belts," and if I'm playing while sitting, I always buckle up.
I've been using another maker's straps, with the buckle in the middle, since I bought my first wooden mountain dulcimer, so putting the dulcimer on or taking it off requires lifting it over my head. Never occurred to me as a problem (except when wearing a big hat) - but, come to think of it, that probably hasn't looked elegant on stage.
Lo and behold, I just tried a Folkcraft strap, and it has buckles right AT BOTH ENDS. Unbuckling it is as easy as reaching for a tuning peg. This must be a godsend for players who have difficulty reaching behind their backs or raising an instrument over their heads!
One note: You may want one for each dulcimer you play frequently, because the leather endpieces are sturdy and take some finger strength to get onto your strap button. No problem - now you know what you want for your next birthday!

It is the best one I have come upon for the Dulcimer I have.
