The velcro horn strap by Leather Specialties is for the player who wants to try a hand strap without marring the finish of their horn. The Clebsch and Alexander Straps both require soldering an 'anchor' on to the horn. This is an inexpensive way to see if this is the route for you to take. Try one of these before you solder on a duckfoot or a permanent hand strap.
I love this product. Allows me to hold the horn without using my pinkie finger. Wonderful.
I bought this strap as a temporary test before permanently mounting a Clebsch strap on my horn. It attached quickly and easily, and does a very nice job relieving the tension on my pinky. Definitely a good, risk-free way to go. Why not just stay with this strap? It's a little thicker than the Clebsch, making it tougher to reach my keys, and I'd have a more comfortable grip with my pinky hook removed. Still, an excellent product.
I was wanting to put a duck foot on my horn, but knowing that Im going to upgrade (hopefully sooner than later, Ive got my eye on a Briz 2000G), I didn't want to drop $70 on a duck foot, then pay and wait on a tech to get it installed. So, seeing that this was both temporary and cheap, I decided to give it a shot. I now recommend it to anyone wanting to try one out. It takes all the weight off of the pinky and makes the horn more comfortable to play. I personally don't like the look of straps, but the added comfort is worth it. you can also still use the pinky ring if you so desire.
